Tin(II) complexes prepared by treatment of SnCl2or Sn(SR)2 with appropriate amounts of RSH and Et3N appear to be the best reducing agents for azides (to amines) reported so far. These tin(II) complexes also reduce primary and secondary aliphatic nitro compounds to oximes, usually within minutes at r.t. or hours in cold, and tertiary aliphatic as well as aromatic nitro compounds to afford the corresponding

alpha,beta-Unsaturated nitroalkenes are readily reduced to the corresponding aldoximes and ketoximes in good yields, using a system of decaborane (B10H14) and DMSO in methanol in the presence of 10% Pd/C at room temperature under nitrogen.
A gene has been isolated from a Rhodococcus sp. encoding an aldoxime dehydratase enzyme useful for the conversion of aldoxime substrates to nitrilases and other downstream intermediates. The gene has been cloned into a recombinant host and expressed.
