Chemistry of β-Triketones. 1. Structure of Schiff Base Intermediates of 2-Acyl-1,3-indandiones

Sawhney, Kailash N.,Lemke, Thomas L.

, p. 4326 - 4329 (2007/10/02)

Schiff base formation has been shown to occur preferentially at the exocyclic carbonyl of 2-acyl-1,3-indandiones (1).The resulting addition product exists either as an open-chain compound (10-16) or as a cyclic hemiketal (19-27).The size of the acyl subst
