tetrakis(triphenylphosphine)platinum(0), allenes undergo carbonylative thiolation with carbon monoxide and thiols to provide the corresponding α,β- and β,γ-unsaturated thioesters in good yields. In contrast, the use of rhodium(I) catalysts such as RhH(CO)(PPh3)3 in place of Pt(PPh3)4 leads to copolymerization of allenes and carbon monoxide without incorporation of thio groups.
在催化量的四(三苯基膦)铂(0)的存在下,丙二烯与一氧化碳和硫醇进行羰基硫醇化反应,以高收率提供相应的α,β-和β,γ-不饱和硫酯。相反,使用铑(I)催化剂如RhH(CO)(PPh 3)3代替Pt(PPh 3)4导致烯丙基和一氧化碳的共聚而不引入硫基。
