Abstract
Reactions involving skeletally stabilized intermediate phosphazanes yield new cyclophosphazanes. Thermolysis of C6H4(NH)2PPh (9) yields (PhP)4 and the λ5 phosphazane [C6H4(NH)2]2PPh (10); 10 upon cyclocondensation with PhPCl2 yields cis,trans- and cis,cis- spiro λ3-λ5-λ3 phosphazanes [C6H4(N)2PPh]2PPh (12). Reaction of the bis(silyl) cyclophosphazane C6H4(NSiMe3)2PPh with PhPCl2 yields triphosphazane C6H4[NP(Ph)Cl]2PPh (13); 13 with 1,2-(NH2)2C6H4 forms cyclotriphosphazane C6H4(N2PPh)(PPh)2C6H 4(NH)2 (14). 14 is the key intermediate in formation of several new [(C6H4N2PPh)]2-(PPh)(PR) (R = Ph, Me) cleft-containing cyclotetraphosphazanes (17). Synthesis and structural characterization of the new phosphazanes are described.
