资源简介：
We report the synthesis of PAlP and
PBP pincer complexes of Rh
with a central bis(N-pyrrolyl)aluminyl or -boryl
unit. Complex (PAlpyP)Rh(CO)2 possesses an aluminyl
site stabilized by coordination of pyridine, resulting in a four-coordinate
Al. Attempts to access the three-coordinate aluminyl by abstraction
of pyridine with BF3·Et2O unexpectedly
led to a B/Al metathesis with the preservation of the pincer structure
in the product (PBP)Rh(CO)2. Abstraction of pyridine was
carried out using B(C6F5)3, but the
desired (PAlP)Rh(CO)2 underwent dimerization via isocarbonyl
bridging.
