Carbenes more than measure up : Singlet stable carbenes compete with transition metals in the activation of enthalpically strong bonds, as shown by the cleavage of the EH bonds of silanes, boranes, and phosphanes (see scheme). However, in contrast with the electrophilic mode of activation observed with metals, carbenes act as nucleophiles towards these substrates. Dipp=2,6‐diisopropylphenyl.
