  Electrophilic and nucleophilic reactions of the vinylidene complex [Cp(PMe3)2Ru:C:C(SMe)2]BF4 and its derivatives

  摘要：

  The cationic vinylidene complex [Cp(PMe3)2Ru = C = C(SMe)2]BF4 (1) undergoes addition of electrophiles such as HBF4.Et2O, [MeSSMe2]SO3CF3, and [Me3O]BF4 to give the complexes ([Ru] = Cp(PMe3)2Ru)[GRAPHICS]An X-ray diffraction investigation shows that 2a crystallizes in space group C2/c with a = 31.558 (5) angstrom, b = 10.492 (2) angstrom, c = 16.484 (5) angstrom, beta- = 100.89 (2)-degrees, and Z = 8. The reaction of 4 with phosphines results in the cleavage of MeS+ to form the sulfonio acetylide [Cp(PMe3)2Ru-C = CSMe2]BF4 (5) and [MeSPPh2R]+ (R = Me, Ph). Anionic nucleophiles such as NaSR (R = Et, Me) displace Me2S from 4 to yield the vinylidene complexes [Cp(PMe3)2Ru = C = (SR)(SMe)]BF4 (R = Et (7), R = Me (1)). Complex 4 also reacts with pyridines, 4-NC5H4R (R = H, Et, NMe2 (DMAP)), and SEt2 to displace Me2S to yield the dicationic vinylidene complexes [Cp(PMe3)2Ru = C = C(4-NC5H4R) (SMe)](BF4)2 (R = H (8), Et (9), NMe2 (10)) and [Cp(PMe3)2Ru = C = C(SEt2)(SMe)](BF4)2 (11). The reactions of DMAP and SEt2 (Nuc) with 4 in CD3CN follow the general rate law rate = kappa-1[4] + kappa-2 [4][Nuc]. The reaction of DMAP is dominated by the kappa-2 pathway, which is proposed to involve nucleophilic attack at the alpha-carbon of 4. The less nucleophilic SEt2 reacts by both nucleophilic (kappa-2) and dissociative (kappa-1) pathways.
