In a convenient and efficient procedure for the solvent-free synthesis of β-hydroxy esters and β-amino esters, various aldehydes and aldimines undergo a Reformatskyreaction mediated by non-activated indium at room temperature to give the corresponding esters in good to excellent yields.

N-Heterocycliccarbenes have been employed as highly efficient organocatalysts to mediate silyl-Reformatsky type reaction. In the presence of only 0.5 mol % nucleophiliccarbene 1, various aldehydes coupled with α-trimethylsilylethylacetate very smoothly in DMF at room temperature to provide the corresponding β-hydroxyesters in moderate to high yields. α-Trimethylsilylketone and α-trimethylsilylamide
