A novel efficient procedure has been developed for the conjugate addition of amines to electron deficient al- kenes. A series of KF supported on different carders have been synthesized for the conjugate addition amines to al- kenes. After optimizing the reaction conditions, KF/MgO was chosen as the most efficient catalyst for the reactions. The results showed that the catalyst was very efficient for the conjugate addition of amines to electron deficient al- kenes with excellent yields in several minutes. Operational simplicity, no need of any solvent, low cost of the cata- lyst used, high yields, reusability, excellent chemoselectivity and wide applicability are the key features of this methodology.

The novel efficient procedure has been developed for the oxathioacetalization of carbonyl compounds and 2-mercaptoethanol using the novel carbon-based sulfonic acid as catalyst under solvent-free condition at room temperature. The results showed that the novel catalyst was very efficient for the reactions with good to excellent yields in short time. The novel catalyst owned many advantages such as operational simplicity,without need of any solvent,small amount of usage,low cost of the catalyst used,high yields,applicability to large-scale reactions,reusability and chemoselectivity over the traditional catalysts,which made the catalyst one of the best choices for the reactions.

A novel efficient procedure has been developed for the conjugate addition of amines to electron deficient alkenes. A series of metal oxides was synthesized for catalyzing the conjugate addition of amines and alkenes. After optimizing the reaction conditions, SrO was chosen as the most efficient catalyst for the reactions. The results show that the catalyst is very efficient for the conjugate addition of amines to electron deficient alkenes with the excellent yields in several minutes. Operational simplicity, without need of any solvent, low cost of the catalyst used, high yields, reusability, excellent chemoselectivity and applicability to large-scale reactions are the key features of this methodology.
