First Titanium‐Catalyzed 1,4‐Hydrophosphination of 1,3‐Dienes

Titanium complexes outshine other catalysts: Titanium complexes have been found to catalyze 1,4-hydrophosphination of dienes, which is thought to proceed through an allyl intermediate (see scheme). Unprecedented regioselectivities (1,4- vs. 1,2-) are reached by using [TiCp2(PMe3)2] or a titanocene complex bearing a pendant phosphine tether as catalysts.
