α-CH acidity of alkyl–B(C(6)F(5))(2) compounds – the role of stabilized borata-alkene formation in frustrated Lewis pair chemistry

Alkyl–B(C(6)F(5))(2) boranes are markedly α-CH-acidic. Using DFT we have calculated the pK (a)-values of a series of examples. Typically, (C(6)F(5))(2)B–CH(3) [pK (a) (calcd) = 18.3 in DMSO, 16.2 in dichloromethane] is almost as CH-acidic as cyclopentadiene. However, this α-CH–B(C(6)F(5))(2) acidity...
