Carboxylic acids => alkynes

Examples of alkylation, dealkylation, homologation, isomerization, and transposition are found in Sections 1,17,33, and so on, lying close to a diagonal of the index. These sections correspond to such topics as the preparation of alkynes from alkynes carboxylic acids from carboxylic acids and... [Pg.16]

Examples of the protection of alkynes, carboxylic acids, alcohols, phenols, aldehydes, amides, amines, esters, ketones, and alkenes are also indexed on p. xvii. Section (designated with an A 15A, 30A, etc.) with protecting group reactions are located at the end of pertinent chapters. [Pg.17]

Further elucidations on the mechanism of alkynes hydration arise from the isolation of both enol and keto tautomers of organometallic intermediates, starting from an alkyne-carboxylic acid ester as tetrolic acid ethyl ester [43]. [Pg.246]
