O-iodobenzoic acid, oxidant and dehydrogenation are very useful. Primary and secondary alcohols are oxidized to corresponding aldehydes and ketones with high selectivity, and unsaturated bonds and amino groups are not oxidized.
Personally, I think this thing is similar to Charette reagent.
TMEDA:
N, N, Nˊ, Nˊ. Tetramethyl ethylenediamine; N, n, Nˊ, Nˊ- tetramethylethylenediamine
Molecular formula: (CH3) 2nnch2ch2 n (CH3) 2
Description: Colorless liquid with strong amine smell. Melting point -55℃. The boiling point is 120 ~ 122℃. The refractive index is 1.4 196. It is miscible with water, alcohol and other organic solvents. Is prepared by refluxing formic acid, ethylenediamine and formaldehyde. It is a polar aprotic solvent. It is also used as an organic synthetic reagent for preparing alkenyl alkynes.
Tips:
Tips is the abbreviation of thermally induced phase separation, which means "thermally induced phase separation" in Chinese. It is a new method for preparing polymer microporous membrane proposed by American a.j.castro in 198 1, and applied for a patent. Its technological process and principle are that the polymer is dissolved in a solvent with high boiling point and low volatility (also called diluent) higher than the melting point of the polymer to form a homogeneous solution. Then cool down. During the cooling process, phase separation will occur in the system. This process is divided into two categories, one is solid-liquid phase separation (referred to as s-l phase separation) and the other is liquid-liquid phase separation (referred to as l-l phase separation). By controlling the appropriate process conditions, after phase separation, the system forms a two-phase structure with polymer as continuous phase and solvent as dispersed phase. At this time, a suitable volatile reagent (extractant) is selected to extract the solvent, so as to obtain a polymer microporous membrane with a certain structure and shape.
I found this online. I don't know if it's the trick you mentioned.
