Abstract: Reaction of cis-1,4-dichlorobut-2-ene with dicyclohexylphosphine in the presence of KI in acetone produces [cis-Cy2PHCH2CH= CHCH2PHCy2]I2, which is converted to cis-Cy2PCH2CH=CHCH2PCy2 on treatment with NaOH. Reactions of cis-Cy2PCH2CH=CHCH 2PCy2 with MHCl(CO)(PPh3)3 (M=Ru, Os) yield MHCl(CO)(PPh3)(Cy2PCH2CH=CHCH 2PCy2). The ruthenium complex RuCl(CO)(PPh 3)(Cy2PCH2CH(CH2) 2PCy2) is obtained by refluxing RuHCl(CO)(PPh 3)(Cy2PCH2CH=CHCH2PCy2) in methanol-CH2Cl2. Reaction of RuCl(CO)(PPh 3)(Cy2PCH2CH(CH2) 2PCy2) with H2 in the presence of NaBPh 4 produces RuHCl(CO)(PPh3)(Cy2P(CH 2)4PCy2). Reaction of OsCl(PPh 3)(2,6-(Ph2PCH2)2C6H 3) with H2 produces OsCl(H⋯H)(PPh 3)(2,6-(Ph2PCH2)2C6H 3) which contains an elongated dihydrogen ligand.
