A number of deuteriated alcohols are rapidly (ca. 1 min) synthesised through the microwave enhanced solid state reduction of the corresponding aldehydes and ketones using alumina doped sodium borodeuteride (NaBD4).

partially dissociated from the ruthenium center (by protonation) in the reaction media, thereby generating a vacant coordination site for catalysis. These studies also show that this substituent increases hydrogenation activity by promoting activation of the reductant. At least three catalytic cycles, involving the decarboxylation of formicacid, hydration of the alkyne, and hydrogenation of the intermediate

(OEt)2PO and Ph; the groups R and R′ were H, Ph and n-C6H13; and the lithiating reagents were n-butyllithium, t-butyllithium and lithium diisopropylamide in donor media of THF or TMEDA. The lithiation occurs with retention of configuration and the resulting lithio-epoxide is unstable above 0°C, decomposing in a carbenoid manner. The lithiation is facile except for compounds where Z and R (an alkyl
