Aluminumdodecatungstophosphate (AlPW12O40), a versatile and a highly water tolerant green Lewis acid catalyzes efficient preparation of indole derivatives
Aluminumdodecatungstophosphate (AIPW(12)O(40)) a highly water tolerant, green Lewis acid has been applied as an efficient catalyst for the preparation of indole derivatives as bis(indolyl)methanes from carbonyl compounds via Friedel-Crafts alkylation and 3-substituted indoles via Michael addition of indole to alpha,beta-unsaturated carbonyl compounds in CH3CN at room temperature.
