Abstract

Starting materials are commercially available (Aldrich, Dalchem, Strem) and were used without purification unless otherwise noted. The quinones and 1,5-bis(bromomethyl)-2,4-dimethylbenzene were obtained according to known procedures. 3,4 (DME)NiBr 2 was prepared by reaction of Ni powder with Br 2 in dimethoxyethane. 5 All synthetic procedures were carried out in evacuated ampoules using freshly purified solvents 6 (except 95% aqueous ethanol which was used ...
