5-Alkyl/arylidenebarbituric acids were efficiently synthesized through an FeCl3·6H2O catalyzed domino reaction of 6-aminouracils, water and aldehydes with water serving a dual role as both solvent and reactant, under benign conditions.
The hypercoordinated tin reagent iPr-tricarbastannatrane is employed in B(C6F5)3-catalyzed transfer 1,4-hydrostannanylation of electron deficient olefins.
