Calculate Digit Verification of CAS Registry Number 134542-39:
(8*1)+(7*3)+(6*4)+(5*5)+(4*4)+(3*2)+(2*3)+(1*9)=115

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

Babudri,Fiandanese,Musio,Naso,Sciavovelli,Scilimati

, p. 225 - 228 (2007/10/02)

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.
