5-Benzylidenecreatinine and 2'-phenylglycocyamidine exist in DMSO-D6 in the imino form.In basic medium, the two compounds exhibit a dual reactivity with respect to methylating agents, forming N(2')- and N(3)-methyl derivatives.
HETEROGENEOUS METHYLATION OF THE SODIUM SALT OF 2-PHENYLIMINO-4-IMIDAZOLIDINONE BY DIMETHYL SULFATE IN ACETONITRILE

The sodium salt of 2-phenylimino-4-imidazolidinone, which exists in acetonitrile in the form of high-molecular agglomerates of spherical form 30-200 nm in diameter, reacts with dimethyl sulfate to form the isomeric exo- and endo-methylation products.Analysis of the kinetic parameters of nucleophilic substitution shows that it takes place on the surface of the agglomerates, i.e., is heterogeneous.
