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

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 c...

Zusammenfassung: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.
