✦ Synopsis


The new compound C 10 H 6 P(S)[NSi(CH 3 ) 3 ] 2 P(S) (3) which contains a P 2 N 2 heterocycle has been prepared in low yield by partial thermal decomposition of 1

3 )SP(S) 2 ] ± (2). Reaction of 2 with potassium hydroxide in acetonitrile gives the completely desilylated product 4). The structures of the new compounds 3 and 4 were elucidated by FTIR and NMR spectroscopy methods and by X-ray structure analyses.
