✦ Synopsis

Disubstituted olefins R1CH:CHR2 can be conveniently prepared from the fragments RCH20H by addition-elimination sequences of which the prototype is the Wittig reaction. By contrast, disubstituted acetylenes R'CiCR2 (1) are usually prepared' from terminal acetylenes R'CfCH by alkylation processes.
