Reaction of the –CH2OSiMe3 substituted allyldimesitylphosphane with HB(C6F5)2 resulted in a hydroboration/(C6F5)2BOSiMe3 elimination sequence to give the phosphinomethyl substituted cyclopropane derivative, probably via a phosphiranium type intermediate.

The conjugated dienamine 4 selectively adds Piers' borane [HB(C 6 F 5 ) 2 ] to give the enamine/borane system 5 , which features a boratirane structure by internal enamine carbon Lewis base to boron Lewis acid interaction. Compound 5 behaves as a C/B frustrated Lewis pair and undergoes typical addition reactions to benzaldehyde, several nitriles and to sulfur dioxide. This article is part of the themed issue ‘Frustrated Lewis pair chemistry’.

Hb C

Twofold hydroboration of the bulky Mes*P(vinyl)2phosphane with Piers’ borane [HB(C6F5)2] followed by C6F5/H exchange with 9-BBN generated a reactive P/B/BH FLP structure that cleanly reduced carbon-monoxide at the trifunctional frustrated Lewis pair framework to the [B]-formyl stage.
