摘要

Reaction between Os(BCl2)Cl(CO)(PPh3)(2) and 2-hydroxypyridine leads to the replacement of one chloride on the dichloroboryl ligand and coordination of the pyridine nitrogen atom to osmium, leading to the six-coordinate complex Os[BCl(OC5H4N)]Cl(CO)(PPh3)(2) (1). The five-membered chelate ring so formed is stable and persists through reactions involving replacement of chloride both at osmium and at boron. When 1 is treated with anhydrous HI, replacement of chloride at osmium occurs exclusively, leaving the B-Cl bond intact and giving Os[BCl(OC5H4N)]I(CO)(PPh3)(2) (2). However, the following nucleophilic substitution reactions at boron occur readily in 1: EtOH gives Os[B(OEt)(OC5H4N)]Cl(CO)(PPh3)2 (3), n-BuNH2 gives Os[B(NHn-Bu)(OC5H4N)]Cl(CO)(PPh3)(2) (4), and Et3N.3HF gives Os[BF-(OC5H4N)]Cl(CO)(PPh3)2 (5). Crystal structures of complexes 2 and 4 are reported. [References: 14]
