资源简介：
The quintuply bonded
α-diimine chromium dimer [HLiPrCr]2 reductively couples cyclohexyl isocyanide
to produce various novel nitrogen heterocycles. Tetramerization yielded,
inter alia, the aromatic squaramidinate, i.e. [C4(NCy)4]2–, whereas hexamerization produces a substituted
1,4-diaza-bicyclo[3.3.0]octadiene dianion. These unprecedented transformations
complement the coupling reactions of isoelectronic CO, and they may
prove synthetically useful.
