A process for the synthesis of N-alkylated lactams via reductive alkylation. The process of the present disclosure may be conducted by the addition of an aldehyde to a lactam in the presence of a catalyst under a reducing atmosphere.

Process for the synthesis of n-substituted lactams and amides

A bleaching composition comprising a peroxy compound and one or more activator present in an effective amount to activate the peroxy compound, present in an amount effective to accomplish bleaching or cleaning or oxidation. The activator is a metallocarbene of the general structure (XX'C)ML&#x2032; where M represents a metal center, C represents the carbene carbon bound to the metal center, X and X&#x2032; may be the same or different and may furthermore be part of a cyclic structure, L&#x2032; represents one or more other ligands which may or may not include one or more metal centers, and where y&#x2267;1.

Metallocarbene complex peroxide activators

A bleaching composition comprising a peroxy compound and one or more activator present in an effective amount to activate the peroxy compound, present in an amount effective to accomplish bleaching or cleaning or oxidation. The activator is a metallocarbene of the general structure (XX'C)yMLn&#x2032; where M represents a metal center, C represents the carbene carbon bound to the metal center, X and X&#x2032; may be the same or different and may furthermore be part of a cyclic structure, Ln&#x2032; represents one or more other ligands which may or may not include one or more metal centers, and where y&#x3e;1.
