Synthesis and properties of phosphorylated 4-methylpyrocatechol derivatives

Procedures for preparing α-phosphorylated 4-methylpyrocatechols were developed. Diphenyl-(3,4-dimethoxybenzyl)phosphine oxide yields diphenyl(3,4-dihydroxybenzyl)phosphine oxide under the action of hydrobromic acid. 2005 Pleiades Publishing, Inc.

Efficient synthesis of benzylphosphine oxides and E-stilbenes

A series of substituted benzylphosphine oxides has been synthesized by reduction of the corresponding (α-chlorobenzyl)phosphine oxide, derived from the benzaldehyde and chlorodiphenylphosphine, with either sodium borohydride (DMSO, 60-70 °C, 12 h) or tributyltin hydride and AIBN (C6H6, 80 °C, 2 h). Reaction of the (α-lithiobenzyl)phosphine oxide with aldehydes gave exclusively E-alkenes.
