A general synthesis for the preparation of alkyl N,N'-beta-diketimines has been developed. The method reported here demonstrates the use of dimethyl sulfate for conversion of enaminoketones to beta-diketimines. The reaction can be performed without solvent, providing good yields.

family of silicon (IV) compoundscontainingN,N'-symmetrically alkyl substituted 1,3-diketimine ligands as chemical vapor deposition (CVD) precursors for silicon-based films has been reported and characterized by 1H, 13C, and 29Si NMR, EI-MS and elemental analysis where necessary. The compounds were synthesized by reaction of corresponding lithium salt of the diketimine ligands and SiMe3Cl according
