摘要

Various cyclic phosphonium structures are formed in high yield by the deprotection of unstable phosphine-aldehydes in acidic solution. When there is a methylene spacer between the phosphine and the aldehyde, a phosphonium ion [PHR2CH2CH (OEt) 2] Br2, R= iPrOH, Et is obtained. Reaction of these phosphonium salts with water produces the dimers [–PR2CH2CH (OH)–] 2 [Br] 2 R= iPr, Et. When there is an ethylene spacer as in ...
