Abstract: New halo compounds of Si and Sn potential precursors of doubly-bonded derivatives of type >E=C=P- (E = 14 main group elements) have been synthesized. Compounds 1-3 (bearing a 2,4,6-tri-tert-butylphenyl group bound to phosphorus and one 2,4,6-tri-methylphenyl radical bonded to Si) are stabilized by the large steric hindrance which prevents the approach of monomers to form dimers or oligomers. | |||||||
