η2-Iminoethyl-C,N vs.η3-aminoethylene-C,C′,N formation in the thermally induced rearrangement of isocyanide alkyl complexes of molybdenum
Abstract
Thermal rearrangement of the isocyanide alkyl complexes [Mo(η5-C5R5)(Me)(CO)2(CNBut)] 1, (R5= H5, 1a; H4Me, 1b; Me5, 1c) yields η2-iminoethyl-C,N complexes [Mo(η5-C5R5){η2-C(NBut)Me3}(CO)2]2, and/or η3-aminoethylene-C,C′,N complexes [Mo(η5-C5R5){η3-H2CC(H)NBut}(CO)2]3, in reactions whose course is dramatically solvent dependent.
