Ru(CO)ClH(C 5H 5N)(PPh 3) 2 reacts with an equivalent of a monosubstituted alkyne in dichloromethane to give alkenyl derivative Ru(CO)Cl(( E)HC CHR)-(C 5H 5N)(PPh 3) 2 (R = n-C 3H 7, n-C 6H 13, n-C 8H 17, CMe 3, Ph, COOMe, COOEt), resulting from a cis-...
A similar product was obtained in the reaction of the alkenyl complex (R = Ph, R′ = CMe3) with Me3CC≡CH in EtOH. Mixtures of both pyrazole alkenyl and alkynyl complexes are formed in the reactions of [Ru-(CO)ClH(Me2Hpz)(PPh3)2] with Me3CC≡CH and pent-1-yne in EtOH. 展开...
Crystals of the title complex have been obtained from SO2 saturated benzene–heptane solutions of Ru(CO)3(PPh3)2, and an X-ray crystal structure determination at –60 °C has shown not only η2-SO2 co-ordination to the ruthenium, but als... David C. Moody,Robert R. Ryan - 《Journal...
