摘要

The dearomatized complex cis-[Re (PNP t Bu*)(CO) 2](4) undergoes cooperative activation of C N triple bonds of nitriles via [1, 3]-addition. Reversible C–C and Re–N bond formation in 4 was investigated in a combined experimental and computational study. The reversible formation of the ketimido complexes (5–7) was observed. When nitriles bearing an alpha methylene group are used, reversible formation of the enamido complexes (8 and 9) takes ...
