Phosphaalkenes : Deoxygenation of oxaphosphirane complexes 1 and 2 by using Ti III complexes gave mixtures of E / Z phosphaalkene complexes 3 a , b and 4 a , b . Theoretical calculations of deoxygenation pathways of 1 revealed that the final products are obtained via intermediate 5 providing the final products by reaction with a second [TiCpCl 2 ] unit and CO bond cleavage (see scheme).
