Tris phosphine TTMPP

Strong Lewis bases such as tris(2,4,6-trimethoxyphenyl)phosphine (TTMPP) and DBLf (1) can catalyse the transformation of cinnamaldehyde to saturated carboxylic acids, whereas mild bases such as triphenylphosphine or tris(4-methoxyphenyl)phosphine give simple cyanohydrin products [85]. When quenching the reaction with alcohol and amine, the corresponding ester and amide are produced, respectively (Scheme 3.44). [Pg.80]

Contra-Peterson elimination also occurred in Morita-Baylis-Hillman-type reactions of 1-silylcyclopropene 101. Addition of the nucleophilic catalyst tris(2,4,6-trimethoxyphenyl)phosphine (TTMPP) at the 2-position of the alkene and condensation of the anion with an aldehyde led to 1,3-Brook rearrangement, with expulsion of the catalyst to regenerate the cyclopropene double bond in product 102. ... [Pg.423]
