Metal-assisted preparation of the alkenyl ketone and carbonyl complexes from 1-alkyne and H2O: C-C triple bond cleavage of terminal alkyne

Reactions of Cp*RhCl2(PPh3) (1) with 1-alkyne and H2O in the presence of KPF6 generated alkenyl ketone complexes [Cp*Rh(CRCHCOCH2R)(PPh3)](PF6) (2) (R = Ph (a), C6H4-p-Me (b), C6H 4-p-COOMe (c), C6H4-p-NO2 (d)). A similar complex [Cp*Rh(CPhCHCOCH2Ph)(PMePh2)] (PF6) (2e) was obtained by use of Cp*RhCl 2(PMePh2). It was revealed by X-ray analyses of 2b, 2c and 2e that the complexes 2 consist of the five-membered ring structures bound by the carbon and oxygen atoms of the alkenyl ketone group. Similar reactions of Cp*IrCl2(PPh3) (6) or (C6Me 6)RuCl2(PPh3) (7) proceeded with a cleavage of C-C triple bond of 1-alkyne without formation of an alkenyl ketone complex, affording the corresponding carbonyl complexes, [Cp*IrCl(PPh 3)(CO)](PF6) (8) or [(C6Me6) RuCl(PPh3)(CO)](PF6) (9). The diphosphine complexes [(Cp*MCl2)2{μ-diphos}] (4: M = Rh, diphos = dppm,; 12a: M = Ir, diphos = dppm; 12b: M = Ir, diphos = dppb) gave a Cl-bridged rhodium complex [{Cp*Rh(μ-Cl)}2{μ-dppm}](PF 6)2 (5), mono-carbonyl or dicarbonyl iridium complexes,[(Cp*IrCl2){μ-dppm}{Cp*IrCl(CO)}](PF 6)(13a) or [{Cp*IrCl(CO)}2{μ-dppb}](PF 6)2 (14b), respectively.

One-step synthesis of alkenyl ketone complexes from CP*RhCl2(PPh3), alkyne and H2O in the presence of KPF6

The reaction of Cp*RhCl2(PPh3) 1 with 1-alkyne and H2O in the presence of KPF6 afforded the alkenyl ketone complex [Cp*Rh(PPh3)(CPh=CHCOCH2R)](PF6) [R = p-tolyl (3a), R = Ph (3b)

Novel ruthenium(II) carbene complexes: Products of the reactions of 1-alkynes with (η6-C6Me6)Cl2Ru(PR3)

Two new η6-C6Me6-phosphine-Ru-CH3CN complexes were synthesized and characterized, and their reactions with terminal alkynes were investigated. The results showed that reactions of the neutral complexes (η6
