WebTin (II) chloride, also known as stannous chloride, is a white crystalline solid with the formula Sn Cl 2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl 2 is widely … Hydrodenitration (replacement of a nitro group with hydrogen) is difficult to achieve but can be effected by catalytic hydrogenation over platinum on silica gel at high temperatures. The reaction can also be effected through radical reaction with tributyltin hydride and a radical initiator, AIBN as an example. Aliphatic nitro compounds can be reduced to aliphatic amines by several reage…
