“…Its spectrum was identical with that of complex [(g 5 -MeC 5 H 4 )Ru(g 3 -PPh 2 CHCH 2 )(g 1 -PPh 2 CHCH 2 )]PF 6 . In particular, no band at 1983 cm À1 , characteristic for m CO of the carbonyl compound [5], appeared in the recovered material, which excludes the formation of carbonyl complex during catalytic reaction.…”

“…In view of the fact that earlier studies of the phosphaallyl [(g 5 -MeC 5 H 4 )Ru(g 3 -PPh 2 CH-CH 2 )(g 1 -PPh 2 CHCH 2 )]PF 6 have shown that the compound may react with phenylacetylene to form a carbonyl compound [(g 5 -MeC 5 H 4 )Ru(PPh 2 CHCH 2 ) 2 (CO)]PF 6 [5], we have decided to check whether such a complex was formed in the conditions of homogeneous hydrogenation of phenylacetylene. For this purpose the homogeneous catalyst was recovered after the reaction and subjected to IR analysis.…”

“…The same complex precursor, by reaction with phenylacetylene in H 2 O, led to a carbonyl ligand, after addition of H 2 O on the vinylidene intermediate. Since reaction stops at the vinylidene step when [Cp*Ru( 3 -DPVP)( 1 -DPVP)] is used, it can be deduced that the C is more electrophilic in complexes bearing MeCp ligand than in those bearing Cp* [161].…”

Alkenylphosphines are compounds of great interest in view of their structures. The most interesting feature is the carboncarbon double bond, which is directly linked to the phosphorus atom. Nucleophilic addition or cycloaddition reactions can take place at this unsaturation, which can also be used as a coordinating part in the presence of a metal. Thus, alkenylphosphines have found numerous applications in various fields of chemistry. They are useful intermediates in organic synthesis: numerous studies are devoted to their transformation into bidentate ligands, to their use as precursors for dendrimer and polymer chemistry or as ligand for homogeneous catalysis. Due to the presence of both the phosphorus atom and the carbon-carbon double bond, they are also of great interest in coordination chemistry and their different bonding modes have been largely documented. Moreover, after complexation to transition metal, a great amount of work has been carried out on their reactivity in cycloaddition reactions, as well as in functionalization of the carbon-carbon double bond and other miscellaneous reactions. These main applications will be reviewed hereafter.

Reactions of Ruthenium–Aminophosphane Complexes with Diynes: P–N Bond Activation and Formation of Novel Phosphaallyl, Azaallyl, and Aminocarbene Complexes

The aminophosphane complexes [RuCp(PPh2NRR′2)(CH3CN)2]+ and [RuCp*(PPh2NRR′2)(CH3CN)2]+ (NRR′ = NHnPr, NEt2, NC5H5) react with 1,6‐heptadiyne and 1,7‐octadiyne to yield novel η3‐phosphaallyl–η2‐vinylamine complexes of the types [RuCp{η3‐(P,C,C)‐PPh2CH=C–(CH2)n–η2‐(C,C)–C=CHNRR′2}]+ and [RuCp*{η3‐(P,C,C)‐PPh2CH=C–(CH2)n–η2‐(C,C)‐C=CHNRR′2}]+ (n = 3, 4). These complexes are the kinetic products but eventually form the η1‐phosphaallyl–η3‐azaallyl complexes [RuCp{η1‐(P)‐PPh2CH=C–(CH2)n–η3‐(C,C,N)‐CCHNRR′2}]+ and [RuCp*{η1‐(P)‐PPh2CH=C–(CH2)n–η3‐(C,C,N)‐CCHNRR′2}]+, respectively. With n = 3 elevated temperatures are required, while with n = 4 this conversion takes places already at room temperature. The only exception is [RuCp*(PPh2NHnPr)(CH3CN)2]+ where amido butadiene complexes [RuCp*{η1‐(N)‐NnPrPPh2‐η4‐CH=C(CH2)nCH=CH2}]PF6 (n = 3, 4) are obtained instead. In the case of [RuCp{η1‐(P)‐PPh2CH=C–(CH2)3–η3‐(C,C,N)‐CCHNRR′2}]+ with NRR′ = NEt2 and NC5H5, a further rearrangement took place at elevated temperatures affording the aminocarbenes [RuCp{=C(NRR′)‐η2‐(C,C)‐C(CH2)3C–CH2–(η1‐(P)‐PPh2)}]+. Representative X‐ray structures are presented. Moreover, conceivable mechanisms for all these reaction sequences are established by means of DFT/B3LYP calculations. (© Wiley‐VCH Verlag GmbH & Co.
