Metal ..cap alpha..-hydroxyalkyls L/sub n/MCH(R)OH, like hemiacetals and other XCH(R)OH species, are unstable. This paper shows that by incorporating X and R into a ring, it is possible to stabilize the ..cap alpha..-hydroxyalkyl system and to synthesize L/sub n/MCH(R)OH (M=Mn, Re) from aldehydes and metal hydrides similar to isolable organic XCH(R)OH compounds. A triarylphosphine ligand was selected
金属..帽α..-羟烷基L/sub n/MCH(R)OH,像半缩醛和其他XCH(R)OH物质一样,是不稳定的。该论文表明,通过将 X 和 R 结合到一个环中,可以稳定 ..cap α..-羟烷基体系并从醛合成 L/sub n/MCH(R)OH (M=Mn, Re)和金属氢化物,类似于可分离的有机 XCH(R)OH 化合物。选择三芳基膦配体用于..cap α..-羟烷基碳与金属的第二个连接。这些化合物应该用于均相催化系统。(DLC)
