A one-pot reaction affords unsymmetrical 1,2-bis(phosphanyl)ethanes 2 and 1,2-arsanyl(phosphanyl)ethanes 3 from the cyclic sulfate 1 in high yield. Similarly, chiral 1,2-bis(phosphanyl)ethanes and 1,3-bis(phosphanyl)propanes could be obtained in enantiomerically pure form. R, R'=alkyl, phenyl.
一锅法反应以高收率从环状硫酸盐1得到不对称的1,2-双(膦酰基)乙烷2和1,2-芳基(膦酰基)乙烷3。类似地,可以以对映体纯的形式获得手性1,2-双(膦酰基)乙烷和1,3-双(膦酰基)丙烷。R,R′=烷基,苯基。
