Abstract

Treatment of 1, 2, 3, 4-tetrahexylbenzene or 1, 2, 4, 5-tetrahexylbenzene with Hg (OOCCF3) 2 produces 1, 2-phenylenedimercury bis (trifluoroacetate) 7 or its 1, 4-isomer 9, which are bidentate Lewis acids. IR studies in CH2Cl2 established that 1, 2-isomer 7 forms doubly coordinated 1: 1 complexes with amides in which both atoms of mercury interact simultaneously with the carbonyl oxygen atom of the bound amide, whereas 1, 4-isomer 9 ...
