(Methoxycarbonylmethyl)triphenylphosphonium bromide, 98+%

Description

CAS: 1779-58-4 | C21H20BrO2P | 415.27 g/mol

(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.
