Abstract: New potential precursors for diphosphaallenes with C=P=C=P skeleton have been synthesized. Compounds 2-4 (bearing a 2,4,6-tri-tert-butylphenyl group bound to phosphorus) are stabilized by the large steric hindrance which prevents the approach of monomers to form dimers or oligomers. | |||||||
