General Description

(2-hydroxypropyl)(triphenyl)phosphonium is a chemical compound that consists of a phosphonium cation with a (2-hydroxypropyl) and triphenyl group attached. The (2-hydroxypropyl) group contains a hydroxy functional group, while the triphenyl group consists of three phenyl groups bonded to the phosphonium cation. (2-hydroxypropyl)(triphenyl)phosphonium is commonly used as a phase-transfer catalyst in organic synthesis reactions, allowing for the transfer of a reactant from one phase to another. Additionally, it can also be used as a precursor for the synthesis of other phosphonium salts and as an intermediate in organic reactions. Overall, (2-hydroxypropyl)(triphenyl)phosphonium plays a crucial role in various chemical reactions and synthesis processes.

Phosphonium salts and aldehydes from the convenient, anhydrous reaction of aryl acetals and triphenylphosphine hydrobromide

The reactions of aryl acetals/ketals and triphenylphosphine hydrobromide gave the corresponding aldehydes/ketones and alkyl phosphonium bromides. This reaction was applied to convert acetals/ketals to the corresponding aldehydes/ketones under an anhydrous

Reaction des oxirannes avec la triphenylphosphine en milieu phenolique

A new access to the vinylphosphonium salts 4 is proposed, using the reaction of epoxides 1 with triphenylphosphine at 100 deg C in phenol.It succeeds very well for the unfunctional epoxides 1 : 2-monosubstituted and 2,3-disubstituted epoxides.In the case of arylepoxides and 2,2-disubstituted unfunctional epoxides, Wittig and " retro-Wittig " side-reactions decrease the yields in vinylphosphonium salts.The reaction of opening epoxides by triphenylphosphine takes place since 40 deg C and is regio and stereoselective.At 40 deg C, the reaction leads to the formation of β-hydroxy alkylphosphonium salts 3.
