A new route to achiral and chiral 1,2-bis(phosphino)ethanes, 1-arsino-2-phosphinoethanes, and 1,3-bis(phosphino)propanes and the molecular structure and catalytic activity of some rhodium(I) complexes derived thereof

A series of unsymmetrical 1,2-bis(phosphino)ethanes R2PCH 2CH2PR′2 (2a-d) and 1-arsino-2- phosphinoethanes R2AsCH2CH2PR′ 2 (3a-c) mainly with bulky substituants R and
A new synthetic route to unsymmetrical 1,2-bis(phosphanyl)ethanes and 1,2-arsanyl(phosphanyl)ethanes with and without a stereogenic center

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.
