Isolation of catalytic intermediates in hydroamination reactions: Insertion of internal alkynes into a zirconium-amido bond

Insert alkyne to continue: Reaction of a bis(ureate) zirconium dimethylamido complex with electron-rich alkynes leads to vinylamine insertion products (see scheme). The insertion of C=C unsaturated bonds into M=N bonds is proposed as a key step in lanthan

The reaction of arylaldehydes with hexamethylphosphorous triamide and the use of the resulting products for the synthesis of enamines and deoxybenzoins

The reaction between the arylaldehydes 1a,b and hexamethylphosphorous triamide 2 leads to the [aryl(dimethylamino)methyl]phosphonic bis(dimethylamides) 3a,b. These can be easily deprotonated by butyllithium in 1,2-dimethoxyethane and condensed with arylaldehydes to afford enamines 4a-f or deoxybenzoins 5a-f in fair to good yield.
