    Novel Metal-Free Hydrogenation of the Carbon−Carbon Double Bond in Azulenoid Enones by Use of Cycloheptatriene and Protic Acid
    摘要:
    [GRAPHICS]An efficient method for the hydrogenation of the carbon-carbon double bond in azulenoid and aromatic fused azulenoid enones without the use of hydrogen and a metal catalyst is reported. Treatment of a variety of azulenoid enones with cycloheptatriene and a protic acid in acetonitrile gave the corresponding, beta-azulenyl ketone derivatives in excellent to moderate yield. In this reaction, cycloheptatriene acts as a hydride donor.
