Regioselective hydrations of 1-aryl-3-en-1-ynes using gold and platinum catalysts: selective production of 2-en-1-ones and 3-en-1-ones†
Abstract
Regiocontrolled hydrations of 1-aryl-3-en-1-ynes have been accomplished with IPrAuOTf and PtCl2/CO to yield 3-en-1-ones and 2-en-1-ones efficiently; our experimental data indicates that the sizes of catalysts play an important role.
