摘要

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.

【期刊论文】Microwave-enhanced Mannich Condensation of Terminal Alkynes, Primary Amines With Paraformaldehyde on Cuprous Iodide Doped Alumina under Solvent Free Conditions

王磊, WANG, Lei*, a, b, LI, Pin-Hua a

CHINESE JOURNAL OF CHEMISTRY 2003, 21, 710-713,-0001,():

-1年11月30日

摘要

A microwave-enhanced, solventless Mannich condensation of terminal alkynes, primary amines with paraformaldehyde on cuprous iodide doped alumina has been investigated. The struc-tures of products depend on the ratio of alkyne to amine and paraformaldehyde.

【期刊论文】The Sonogashira coupling reaction catalyzed by ultrafine nickel(0) powder

王磊, Lei Wang, *a b Pinhu a Lia and Yicheng Zhang a

Chem. Commun., 2004, 514-515,-0001,():

-1年11月30日

摘要

The Sonogashira coupling reaction catalyzed by ultrafine nickel(0) powder has been developed; terminal alkynes couple with aryl, alkenyl iodide and aryl bromide in the presence of cuprous iodide, triphenylphosphine, potassium hydroxide and ultrafine particle nickel(0) to provide the corresponding crosscoupling products with high yields.
