Abstract

A high yield synthesis of tetraselenafulvalene (TSF) involving a novel acid catalysed exchange reaction between d i se I en i d esand b i s ( N, Nd ia I ky I se I en oca r ba mo y I ) se I enid es is re po rt ed . ... The recent discovery of superconductivity in cation radical salts of tetramethyltetraselenafulvalene' has increased the interest in the synthesis of tetraselenafulvalenes (TSF's). Key intermediates in the synthesis of substituted TSF's are 2-oxoalkyl N, N- ...
