【期刊论文】A novel preparation of methyl ketones through one-carbon homologation of aldehydes
王磊, Lei Wang, a, b, * Pinhua Li, a Jincan Yana and Zhongzhi Wuc
Tetrahedron Letters Pergamon 44(2003)4685-4688,-0001,():
-1年11月30日
A novel two-step aldehyde homologation procedure for the preparation of methyl ketones has been developed, which involves the use of 1,1-dibromo-1-alkenes as precursors and zinc metal as mediator in near-critical water.

【期刊论文】Rapid microwave-enhanced, solventless Sonogashira coupling reaction on alumina
王磊, George W. Kabalka, * Lei Wang, Vasudevan Namboodiri and Richard M. Pagni
Tetrahedron Letters 41(2000)5151-5154,-0001,():

An unexpected samarium metal mediated chemoselective debromination and reduction of 1,1-dibromo-1-alkenes in methanol has been developed, which generates vinyl monobromides, alkenes, and alkanes respectively with appropriate molar ratio of samarium to 1,1-dibromo-1-alkene.
