PREPARATION AND CHARACTERIZATION OF STERICALLY PROTECTED PRIMARY PHOSPHINE SULFIDE AND OXIDE

Sterically protected primary phosphine sulfide (1) and oxide (3), were prepared from 2,4,6-tri-tert-butylphenylphosphine (2) and were characterized as stable compounds.

SYNTHESIS OF ALKENES FROM PHOSPHAALKENES AND CARBONYL COMPOUNDS

The present invention is a method for the reductive coupling of carbonyl compounds to selectively prepare unsymmetrical alkene(s). In a first step of the method according to the invention, a phosphorus reagent, such as a phosphanylphosphonate, a phosphoranylidenephosphane, or a silylphosphane, is used to convert the first carbonyl compound to a λ3 σ2 phosphaalkene intermediate. This phosphaalkene intermediate is activated by the addition of a base such as hydroxide or alkoxide, potentially under oxidizing conditions, and then reacted with a second carbonyl compound to form the alkene. The first and the second carbonyl compounds may be different from each other, substituted and selected from the group consisting of aldehydes, such as aromatic or aliphatic aldehyde, or ketones, such as aromatic or aliphatic ketones. In such a case, an unsymmetrical alkene is selectively formed. The invention also embraces any alkene compound prepared as taught by the present application. Another aspect of the invention is a kit of parts for the reductive coupling of a first and a second (substituted) carbonyl compound to selectively prepare unsymmetrically substituted alkene(s).
