Isocyanates react with isopropyl or sec-butylmagnesium bromide in the presence of a small amount of Cp2TiCl2 to afford amides with normal alkyl group.A possibl mechanism for this reaction is proposed.

Herein we report the functionalisation of aldehydes via hydroacylation of azodicarboxylates. A range of functionalised aldehydes are employed as the limiting reagent including chiral non-racemic aldehydes bearing α-stereocentres which are functionalised giving access to enantiomerically pure products. The resultant hydrazides can be employed as acyl donors in the synthesis of amides.
