w-Hydroxyalkylphosphonium salts as "instant-ylide" components: extremely convenient and highly cis-selective synthesis of alkenol-type pheromones
1985
Abstract
(Z)-Me(CH2)mCH:CH(CH2)nOH (m = 3,4, 6-9; n = 5-12) were prepd. in 69-84% yield by treating Me(CH2)nCHO with Ph3P:CH(CH2)nONa, formed in situ by treating mixts. of Ph3P+CH2(CH2)nOH Br- with paraffin- or butadiene-styrene-divinylbenzene copolymer-coated NaNH2 with THF. [on SciFinder (R)]
