    • This invention provides a process for preparing lactams, by selectively reacting a novel 1-hydrocarbyl-amino (or heteroatom-substituted hydrocarbylamino); 1,1-dicarboxylic acid, alkylesters; 1-hydrocarbyl (or heteroatom-substituted hydrocarbyl) carboxylic acid, alkyl ester methane, as the salt of an acid having a pKa of 0 or more, in the absence or presence of a base, whereby novel lactams wherein one or both hydrocarbyl moieties are incorporated into the lactam ring are obtained. That is, the acid moiety of said novel salt promotes the reaction whereby both hydrocarbyl moieties are incorporated into the ring, while the presence of a base, in an amount substantially equivalent to said acid promotes the reaction whereby only one hydrocarbyl is incorporated into the ring.
