Unique pathway: The radical‐initiated addition polymerization of MesP=CPh2 propagates through the ortho‐bound CH3 group of the Mes moiety after CH bond activation (see scheme, Mes=2,4,6‐trimethylphenyl, tht=tetrahydrothiophene, TEMPO=2,2,6,6‐tetramethyl‐l‐piperidinoxyl). This unique isomerizationpolymerization mechanism contrasts the previously suggested head‐to‐tail enchainment typically observed

Syntheses of the phospha-alkene complexes cis- and trans-[PtCl2(PEt3)(mesityl)P=CPh2], and cis- [PtX2(Mesityl)P=CPh2}2](X=Cl, I, Me) complexes are reported. 31P NMR spectra indicate that bonding of the phospha-alkene to the metal is via the phosphorus lone pair and this is confirmed by a single crystal X-ray diffraction study of cis-[PtCl2(PEt3)(mesityl)P=CPh2}]CHCl3.

The first examples of co-ordination complexes containing a phospha-alkene are described; n.m.r. studies on cis-M(CO)4L2(M = Cr,Mo,W), trans-RhCl-(PPh3)2L, trans-RhCIL2(CO), Rh(η5-C9H7)L2, cis-PtX2L2(X = Cl,I,Me), and cis- and trans-PtCl2(PEt3)L, [L = P(mesityl)CPh2], suggest that co-ordination to the metal is via the phosphorus lone pair.
