- W2015990195 abstract "Methyl and ethyl di-t-butylphosphinite have been prepared and reactions of the latter with a number of alkyl halides investigated. Normal Arbuzov products, But2RPO, are the predominant or sole products for RX = Mel, Etl, PhCH2Br, Br(CH2)3Br, BrCH2CH2OPh, ClCH2COOEt, and ClCH2CONH2. For RX = ClCH2CN, CH2I2 and BrCH2CH2Br the main products are But2P(O)X, and for RX = ClCH2COCH3 and ClCH2P(O)Ph2 both products are formed. The reaction mixtures have been analysed mostly by 1H n.m.r. spectroscopy, and major products have been isolated and characterized and plausible reaction pathways outlined. It is shown that But2P(O)X arises from attack of But2POEt on the halogen of RX, the pronounced halogenophilicity of But2POEt being ascribed to steric hindrance from the t-butyl groups." @default.
