Preparation of methyl chalcogenated derivatives of 1,4,5,8-tetrathiatetralin
Abstract
Tetrakis(methylthio)-1,4,5,8-tetrathiatetralin 4 and tetrakis (methylseleno)-1,4,5,8-tetrathiatetralin 6 is successfully prepared by the reaction of tetrathiatetralin (TTT)2 with lithium diisopropylamide and MeSSMe or MeSeSeMe in diethyl ether and a remarkable solvent effect is observed in the analogous reaction in tetrahydrofuran to give tetrakis(methylthio)tetrathiafulvalene 5 by a novel rearrangement.
