Abstract
1,2 lambda(5)-azaphosphete 1 reacts with cyclohexylamine leading to fi ve-membered phosphazenes 7 and 8. This result has been rationalized by the protonation of the ring nitrogen atom followed by nucleophilic ab ack of the amide at the P-carbon of the ring. Addition of p-cresol and p-thiocresol to 1 affords the linear phosphazenes 12 and 13, resultin g from protonation of the a-carbon atom of the ring followed by nucleo philic aback at phosphorus. Compounds 7 and 12 have been characterized by single crystal X-ray diffraction studies.
