1,3,4-Oxadiphospholanes and 1,3,4-Thiadiphospholanes from Diphosphorus-substituted 2-Oxa- and 2-Thia-propanesThe synthesis of phosphonates and phosphinates of the type (RO)2(O)PCH2ZCH2P(O)(OR)2, R1(RO)(O)PCH2ZCH2P(O)(OR)2 and R1(RO)(O)PCH2ZCH2P(O)(OR)R1 (with Z = O, S; R = Et, Pri; R1 = Me, Ph) is reported. Acyclic diphosphanes, R1(H)PCH2ZCH2P(H)R2 (with Z = O, S; R1 = R2 = H, Me, Ph; R1 = H, R2 = Me), and 1,3,4-Oxadiphospholanes as well as 1,3,4-Thiadiphospholanes are obtained from the esters by reduction.
Notes:
Die Darstellung von Phosphonaten und Phosphinaten der Zusammensetzung (RO)2(O)PCH2ZCH2P(O)(OR)2, R1(RO)(O)PCH2ZCH2P(O)(OR)2, und R1(RO)(O)PCH2ZCH2P(O)(OR)R1 (mit Z = O, S; R = Et, Pri; R1 = Me, Ph) wird beschrieben. Durch Reduktion der Ester sind die acyclischen Diphosphane, R1(H)PCH2ZCH2P(H)R2 (mit Z = O, S; R1 = R2 = H, Me, Ph; R1 = H, R2 = Me) und 1,3,4-Oxadiphospholane bzw. 1,3,4-Thiadiphospholane zugänglich.
