Phosphinidenes are P-analogue of carbenes where P is monovalent with
incomplete octet of electrons around it. Free phosphinidenes do not show
any reactivity and are highly unstable.They show enhanced stability and reactivity
when complexed with organometallic moieties like M (CO)5 (M= Cr, Mo, W). The
2H azaphosphirene complex (1) is one of the precursors known to generate
the elcetrophilic phosphinidene complex (2) in situ and it is very effective
in this approach. Recently, we found that terminal phosphinidene tungsten
pentacarbonyl complexes (2) reacted efficiently with the reagents containing no
π-systems. For example, a reaction of terminal phosphinidene complex (2) with
CCl4 resulted in halogen atom transfer from carbon to phosphorus. Following
these results, we run a few reactions of (2) with substrates containing a single
carbon-halogen bond like RX (C6H5CH2 or Me; X= Cl, Br or I) and in all cases, only
a single prochiral product was formed selectively as a result of the insertion-
reaction of phosphinidene complexes (2) into a carbon-halogen bond. This
method has provided a novel route for one step selective synthesis of prochiral
organophosphorus compounds.
