| Abstract | A simple and efficient procedure was developed for the preparation of [(Ph(3)P)(4)Rh-2(mu-OH)(2)], 1, from Wilkinson's catalyst and aqueous KOH under biphasic conditions (75-85% yield). Complex 1 reacted with cyclopentadiene, methyl malonate, and benzoic acid to give [CpRh(PPh(3))(2)], [(Ph(3)P)(2)Rh(CH(COOMe)(2))], and [(Ph(3)P)(2)Rh(mu-PhCOO)], respectively. Depending on the amount of formic acid, the reaction between 1 and HCOOH resulted in either decarboxylation and formation of [(Ph(3)P)(2)Rh(H)(2)(HCOOO)] or dehydration affording trans-[(Ph(3)P)(2)Rh(Co)(HCOO)], 6 both transformations being chemospecific. Treatment of 1 with [CpM(CO)(3)H] (M = Cr, Mo, W) gave heterobinuclear complexes, [(Ph(3)P)(2)Rh(mu-Co)(2)M(CO)Cp], in excellent yield. The structure of 6 was confirmed by X-ray analysis. |
