Mass fragmentation pattern of some mono- and di-substituted formamidines. Part-1. Mass pattern of 1-arylformamidines

Some 1-arylformamidines were prepared by the Raney nickel (W-2) desulphuration of some 1-arylthioureas in anhydrous boiling benzene medium. Mass fragmentation patterns of the products were ascertained from the mass spectral data.

Raney Nickel Desulphuration of 1-Substituted- and 1,3-Disubstituted-thioureas

Certain 1-aryl-1,3-diaryl- and 1-aryl-3-tetra-O-acetyl-β-D-glucopyranosyl thioureas have been successfully desulphurated into the related mono- and 1,3-di-substituted formamidines with the help of Raney nickel catalyst.A few of them have been converted into the corresponding formamides also.Structure of the products have been established through usual chemical transformations, ir, nmr and mass spectral analysis.
