Hydrosilylation of secondary and tertiary amides to amines is described using catalytic amounts of B(C6F5)3. The organic catalyst enables the reduction of amides with cost-efficient, non-toxic and air stable PMHS and TMDS hydrosilanes. The methodology was successfully extended to the more challenging reduction of primary amides.

Triple bonds do it! The molybdenum‐catalyzed CN bondcleavage of organic amides with hydrosilanes to produce alcohols and amines has been investigated. This work complements previously established protocols that lead to the cleavage of the CO bond. Modified triply bonded dimolybdenum(III) alkoxides have been found to be crucial for tuning the selectivity to CN bondcleavage (see figure).
While the iron is hot: The first general and efficient iron‐catalyzed reduction of secondary and tertiary amides into amines using polymethylhydrosiloxane (PMHS) has been developed (see scheme).

The platinum-catalyzed hydrosilylation of amides to afford amines selectively is reported. By using defined platinum/N-heterocycliccarbene complexes, the reduction of secondary and tertiaryamines takes place under mild conditions.
