Effects of HgCl2 and W(CO)5 coordination on the structure of a 1,2-dihydrophosphete (phosphacyclobutene)

The synthesis and structural characterization of 1,3,4-triphenyl-1,2-dihydrophosphete and its complexes with mercuric chloride and tungsten pentacarbonyl are reported. Changes in bond lengths and angles upon metal coordination are consistent with an increased bonding contribution from the phosphorus s orbital. This rehybridization is supported by 1H, 13C, and 31P NMR spectral studies. Metal coordination does not lead to any significant skewing of the geometry of the phosphacyclobutene ring toward the corresponding ring-opened 1-phosphabutadiene form, and in fact may have the reverse effect.
