As the phosphorus analogues of alkylidene(or carbene)and imido(or nitrene)complexes,phosphinidene complexes have received much attention.A great number of phosphinidene complexes have been synthesized
Rare-earth amides and alkyls display unique chemical properties because of the highly Lewis acidic metal ions,and thus are very useful for catalytic hydroelementation reactions by σ-bond metathesis wi
