Tetrahedron Letters 1985, 26, 157, Abstracts of Paper, For example, reaction of2a with a large excess of 1,2-diaminoethane (pyridine, room temperature, 8 h) leads to1c (80–90%). b. During the course of our research, two reports appeared on displacement reactions for ditosylate2b (and ditriflate2c) for the preparation of substituted anthracene-9,10-diones. The difluoride2a undergoes displacements much more readily than either of these substrates. See
