Reductivealkylation of aromaticamines with 2-methoxypropene using 1.0 equivalent of HOAc and NaBH(OAc)3 in 1,2-dichloroethane (DCE) at room temperature furnished N-isopropyl amines in 50-98% yields. This method was successfully extended to trimethylsilyl enol ethers. The mild reaction conditions provide a new alternative procedure for the reductive amination of electron deficient aromatic amines

azide, gives indazolo[3,2-b]benzothiazole by attack on the benzothiazole nitrogen. Similar attack of the nitrene in 2-(2-nitrophenyl)benzimidazoles gives benzimidazoindazoles in good yield. However, with an appropriate 1-substituent in the benzimidazole (e.g. Me or CHMe2) the nitrene in its triplet state (generated by acetophenone-sensitised photolysis or by thermolysis of the azide bearing a 4-dimethylamino-group)
