So I've been doing very intense cardio and sports on opiates, mainly cycling. I feel like I can cycle at a higher intensity because the pain is taking away, I don't feel the burn and exhaustion as much. However they are still there. I noticed that my quads have been exceptionally sore lately. This shouldn't happen with biking because there is no negative tension in the movement. Also I breath 20-30% less hard than when I bike sober. Could the soreness be related to lack of oxygen? Can I be doing damage.
Also when not taking opiates my fingers hurt a lot and I have tingling and numbness over my arm and hands, like carpal tunnel syndrome. This is absent on opiates. Did anyone experience this? Could it be related to lack of oxygen?

Across the world, lakes are experiencing deoxygenation due to the climate crisis.
According to a study by the journal nature, long-term declines in dissolved oxygen concentrations in coastal and ocean waters have been linked to climate warming and human activity, but little is known about the changes in dissolved oxygen concentrations in lakes.
Researchers [of this study] observed temperatures across both surface water and deep waters levels, as well as the concentration of dissolved oxygen — the most important gas in aquatic ecosystems, writes The Hill.
“The new study provides a much-needed global overview of what happens in the limited freshwater stores of the planet – their health is a prime concern. Climate change, together with [agricultural pollution], threatens vulnerable freshwater systems, adding to the urgency to strongly cut emissions,” says Hans-Otto Poertner, a professor at the Alfred Wegener Institute in Germany.
Previous studies have shown falling oxygen levels in individual lakes, but this study is the first to look at so many lakes globally, as researchers gathered data from nearly 400 lakes in the United States, Canada, Europe, Asia and South America. The study found that in the past 40 years, oxygen levels have fallen nearly 19% in deep waters and 5% in surface waters, which is up to nine times faster than the oxygen loss in oceans, reported EcoWatch.
The deoxygenation of these lakes is hazardous for the lakes’ ecosystem by suffocating wildlife and changing the physical and chemical environment. Drinking water is also threatened when oxygen levels change.

This mild and environmentally friendly strategy provides an unprecedented and efficient access to the Wolff rearrangement reaction which traditionally entails 𝛼-diazoketones as the precursors. The resulting ketenes could be precisely trapped by alcohols/thiols to give 𝛼-aryl (thio)acetates and by imines to afford the valuable 𝛽-lactams in up to 99% yields.

First some warnings:
This post involves a theoretical reaction with significant scientific backing, some reactions are unverified and may be dangerous. Do not attempt this reaction without significant experience and further research.
This post's main reducing agent is a potentially energetic compound (on the order of RDX, tetrazoles, or nickel hydrazine nitrate) and care should be used when handling it. It has favorable (high temperature tolerance) properties and would likely be a secondary explosive though the energy released from any uncontrolled reaction would be instantaneous (its a polymer) and would involve the release of a toxic, pyrophoric gas, along with an equa-molar amount of hydrogen.
UNDER NO CIRCUMSTANCES SHOULD THIS COMPOUND BE MIXED WITH A COMPOUND THAT HAS STRONG OXIDIZING CAPABILITIES. The energy released by the reaction of hydrogen/oxygen and active boron/oxygen generates enough force to launch rockets (as does active oxygen/hydrazine).
Any attempt to synthesize this compound with malicious intent (utilizing its energetic properties rather than the reducing properties) will not receive a response from me.
This post is going to be quite long as many of my other are so I will add a line (such as the ones above) when I change topics. Enjoy.
So I'm sure many of you have seen my post on reducing agents, (if not you should definitely check it out) and at the end I made a claim about the reducing capabilities of hydrazine, more specifically in the form of metal hydrazides. Unfortunately metal hydrazides are very unstable and cannot be stored. They are also difficult to make (without a detonation) and have unverified reducing capabilities other than catalyst free hydrogenation of alkenes and alkynes (very impressive).
I was researching boron sulfide as a possible reducing agent (dead end) and came across an article that claimed that with heating and high pressures that boron trihalides could be converted to a triamide. This is interesting because boron has trouble forming bonds with nitrogen that are not boron nitride or a lewis adduct.
I then looked into this reaction with hydrazine and found a pivotal piece of literature. The article asserts that hydrazine and boron trihalides react in a way analogous to ammonia and trihalides ([link](https://cdnsci

In the Barton deoxygenation reaction, since the alcohol ultimately turns into a radical intermediate in the mechanism before generating the alkane product, does that mean that tertiary and secondary alcohols work best with this reaction instead of primary alcohols? That being said, do phenols not react at all? Thanks!

Ion pairs in control : Certain ion pair intermediates can be made more reactive when electrostatic forces between a reactive cation and anion can couple with productive C−O bond‐cleaving processes. Low dielectric media can enhance such forces. This approach led to a diverse range of products being obtained from the one‐step, high‐yielding, catalytic transformation of mono‐, di‐, and oligosaccharides. BCF=tris(pentafluorophenyl)borane.
Abstract
Controlling which products one can access from the predefined biomass‐derived sugars is challenging. Changing from CH2Cl2 to the greener alternative toluene alters which C−O bonds in a sugar are cleaved by the tris(pentafluorophenyl)borane/HSiR3 catalyst system. This increases the diversity of high‐value products that can be obtained through one‐step, high‐yielding, catalytic transformations of the mono‐, di‐, and oligosaccharides. Computational methods helped identify this non‐intuitive outcome in low dielectric solvents to non‐isotropic electrostatic enhancements in the key ion pair intermediates, which influence the reaction coordinate in the reactivity‐/selectivity‐determining step. Molecular‐level models for these effects have far‐reaching consequences in stereoselective ion pair catalysis.
