WebStannous chloride catalyzes a chemoselective reductive amination of various carbonyl compounds with aromatic amines using inexpensive polymethylhydrosiloxane as reducing agent in methanol. The present method is applicable for the synthesis of tertiary and secondary amines. see article for more examples Key Words reductive amination , PMHS In organic chemistry, SnCl 2 is mainly used in the Stephen reduction, whereby a nitrile is reduced (via an imidoyl chloride salt) to an imine which is easily hydrolysed to an aldehyde. The reaction usually works best with aromatic nitriles Aryl-CN. See more Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula SnCl2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot.
