Organische Phosphorverbindungen XV. Eine neue Methode zur Darstellung von Aminophosphinen und einige ihrer Reaktionen

The reaction of (CH 3 ) 2 NPCl 2 , [(CH 3 ) 2 N] 2 PCl, Et 2 NPCl 2 and C 6 H 5 (CH 3 )NPCl 2 with organoaluminum compounds, (CH 3 ) 3 Al, Et 3 A1, Et 2 AlCl, EtAlC1 2 and iso ‐Bu 3 Al, has been studied. The preparation of dialkylamino‐dialkylphosphines, R 2 PNK′R″ (R CH 3 , Et, i ‐Bu; R′R″ CH 3 , Et; R′ CH 3 ; R″ C 6 H 5 ), and bis‐dialkylamino‐alkyl‐phosphines, RP(NR′ 2 ) 2 (R Et, i ‐Bu, R′ CH 3 ), and their reaction with alcohols and PC1 3 is described. The preparation of some unsymmetrical tertiary phosphine oxides, R 2 R′PO (R CH 3 , Et; R′ C 12 H 25 ) is also reported. In addition, results on the reaction of PC1 3 with Et 3 A1 and CH 3 AlCl 2 are presented.
