Birch reduction alkyne
WebBirch reduction. The first successful hydrogenation of C 60 was achieved by Smalley and coworkers using a Birch reduction process (Li, liquid NH3, and t -BuOH) [6]. In experiment, the dark-colored C 60 was converted to a light cream to off-white substance. Spectral analysis indicated the existence of isomers of C60 H 36 and C 60 H 18.

WebBirch reduction. The Birch reduction is an organic reaction that is used to convert arenes to 1,4-Cyclohexadiene. The reaction is named after the Australian chemist Arthur Birch and involves the organic reduction of aromatic rings in an amine solvent (traditionally liquid ammonia) with an alkali metal (traditionally sodium) and a proton source ... WebNotes on Birch-like Reductions. by Chem Guy. Aurther Birch wrote about the reduction of benzyl alcohols in "The Journal of the Chemical Soceity" (1945 page 809) .

An Na radical donates an electron to one of the P bonds in a carbon-carbon triple bond. This forms an anion, which can be protonated by a hydrogen in an ammonia solvent. This prompts another Na radical to donate an electron to the second P orbital. fitsword.comWebThe Birch reduction is the name given to this useful reaction.
