Paper Chromatography of Aldehydes and Ketones

Magnesium-catalysed hydroboration of aldehydes and ketones.

The heteroleptic magnesium alkyl complex [CH{C(Me)NAr}(2)Mg(n)Bu] (Ar = 2,6-(i)Pr(2)C(6)H(3)) is reported as a highly efficient pre-catalyst for the hydroboration of aldehydes and ketones with pinacolborane.

Reduction of Aldehydes and Ketones with LiBH4 Under Microwave Irradiation

A variety of aldehydes and ketones have been reduced to their corresponding alcohols within 30-240 secondswith excellent yields (92-97%) of products by LiBH4 under microwave irradiation in H2O as green solvent.
