Abstract

Abstract 4-Methyl-1,2,6-triphosphatricyclo[2.2.1.02.6]heptane, CH3C(CH2P)3 (1) reacts with sulfur or selenium in the molar ratios of 1:3, 1:5 and 1:6 to yield the chalcogeno-dichalcogenatriphosphanoradamantanes CH3C (CH2P)3E2(E ) (E = S, Se; 2a, b), the dichalcogeno-trichalcogenatriphospha- adamantanes CH3C(CH2PE)3(E)2 (E = S, Se; 3a, b) and the trichalcogeno-trichalcogenatriphospha- adam antanes CH3C(CH2PE)3(E )3 (E = S, Se; 4a, b). The selenium derivative 4b could be detected only by 31P{1H} NM R spectroscopy. Main product in the 1:6 reaction of 1 with selenium is 3b.
