The Electrophilic Behavior of Stable Phosphanylcarbenes Towards Phosphorus Lone Pairs.
As expected for a singlet carbene, the stable phosphanylsilylcarbene 1 possesses an accessible vacant orbital, as shown by reactions with Lewis bases such as phosphanes and a bimetallic complex containing a side-on-coordinated full blockC:full blockP identical withPfull blockC:full block moiety (see the reaction scheme). R=cHex(2)N.
