Pentamethylcyclopentadienyl-rhodium and -iridium complexes. Part 18. The reactions of [M(C5Me5)(sol)3][PF6]2(M = Rh or Ir; sol = MeCn, Me2CO, or MeOH) with Mono-, Di-, and Tri-olefins

Abstract

Reaction of [M(C5Me5)(MeCN)3][PF6]2(1; M = Rh or Ir) with bicyclo[2.2.1]heptadiene (nbd) gave [M(C5Me5)(nbd)(MeCN)][PF6]2. Cycle-octa-1,5-diene (cod) underwent deprotonation when treated with (1) or [M(C5Me5)(Me2CO)3][PF6]2, (3), to give the 1–3:5,6-η-cyclo-octadienyl complexes [M(C5Me5)(C8H11)][PF6](M = Rh or Ir); the iridium complex underwent hydride attack by [BH4] to give [Ir(C5Me5)(cod)]. Cyclopentadiene, dicyclopentadiene, and propene were all complexed with deprotonation on reaction with (3) to give [M(C5Me5)(C5H5)][PF6], the 1–3:5,6-η-(4,7-methano)-3a,4,7,7a-tetrahydroindenyl complexes, [M(C5Me5)(C10H11)][PF6](M = Rh or Ir) and [Ir(C5Me5)(η3-C3H5)(η2-C5H5)][PF6] respectively. In contrast, cycloheptatriene underwent nucleophilic attack by the solvent when treated with [M(C5Me5)(YH)x][PF6]2[3; YH = Me2CO, M = Rh or Ir; YH = MeOH, M = Rh] to give the 6-exo-acetonyl- or 6-exo-methoxy-1–5-η-cycloheptadienyl complex [M(C5Me5){C7H8(Y)}][PF6]. The 1H and 13C spectra of the products are discussed.
