Phosphinimine-substituted boranes and borenium ions

30 September, 2014 - 14:54

Dalton Trans., 2014, 43,15201-15211
DOI: 10.1039/C4DT02406K, PaperMichael H. Holthausen, Ian Mallov, Douglas W. Stephan
Phosphinimines R3PNSiMe3 (R = alkyl, aryl) are reacted with a series of chloro and fluoroboranes (9Cl-9-BBN, (C6F5)2BCl, PhBCl2 and Mes2BF) to access a family of phosphinimine-substituted boranes via Me3SiX elimination (X = Cl, F). Subsequent methylation of the imine-N atom using MeOTf yielded phosphinimine-substituted borenium ion salts.
