| titleOfInvention | Method for generating secondary phosphines |
| abstract | This invention provides a method for generating secondary phosphines from secondary phosphine oxides in the presence of a reducing agent, such as diisobutylaluminum hydride (DIBAL-H), triisobutyldialuminoxane, triisobutylaluminum, tetraisobutyldialuminoxane, or another reducing agent comprising: (i) an R 1 R 2 AlH moiety, wherein R 1 and R 2 are each an alkyl species or oxygen, and wherein at least one of R 1 or R 2 comprises at least 2 carbon atoms, or (ii) an R 1 R 2 R 3 Al moiety, wherein R 1 , R 2 , and R 3 are not hydrogen, and wherein at least one of R 1 , R 2 , and R 3 is an alkyl species comprising a β-hydrogen, not including triethylaluminum. Preferred reducing agents for the present invention include: diisobutylaluminum hydride, triisobutyldialiuminoxane, triisobutylaluminum, tetraisobutyldialuminoxane, and combinations thereof. |
