white powder | [Uses]
(Methoxycarbonylmethyl)triphenylphosphonium bromide is a reactant for the synthesis of GSK-3 inhibitors using the Wittig reaction, substituted furanones for antifungal and cytostatic activities, photochromic dithienylethene derivatives, gem-diiodoalkanes containing allylic alcohols and highly substituted cyclopentenes and brazilanes via Au-catalyzed deoxygenative Nazarov cyclization. As reactant for asymmetric hydrogenation of α,β-unsaturated ester-phosphonates, studies of thermal decomposition of phosphonium alkyl ester salts. | [Purification Methods]
Wash it with pet ether (b 40-50o), recrystallise it from CHCl3/Et2O and dry it at high vacuum at 65o. [Isler et al. Helv Chim Acta 40 1242 1957, Wittig & Haag Chem Ber 88 1654, 1664 1955, Beilstein 16 IV 981.] |
