Phosphorane trimethyl methylene

Ebsworth and coworkers have determined the structures of trimethyl(methylene)phos-phorane (29)60, trimethyl(silylmethylene)phosphorane (30)61 and hexamethylcar-bodiphosphorane (31 )38 in the gas phase using electron diffraction techniques. A summary of some of their results is given in Table 6 and schematic drawings of these structures are given in Figure 8. [Pg.289]

Similar compounds can be obtained from dimethyl(methylene)(trimethyl-phosphoranylideneamino)phosphorane. Reacting this diylide in ether with a cold (0°C) solution of Me3Ga-OEt2 evolves no gas, but after 2 h at RT a cristalline 1 1 adduct can be isolated from pentane. When this compound is heated and refluxed in benzene for 2 h, CH4, is evolved and heterocyclic compounds are formed. [Pg.268]
