SULFURATION OF CYCLOPOLYPHOSPHINES WITH PHOSPHONOTRITHIOIC THIOANHYDRIDES
Andreev, N. A.,Grishina, O. N.
, p. 1365 - 1367 (2007/10/02)
The sulfuration of cyclopolyphosphines with bisphosphonotrithioic bisthioanhydrides leads to the formation of 2,4,5-triorgano-1,3,2,4,5-dithiatriphospholane 4-sulfides.
