A copper (II) (II) composite chlorinating agent and copper-based composite chlorinating agent synthesis of 1-chloro-2-aryl acetylene method

The invention discloses a copper (II) composite chlorinating agent and a method for synthesizing 1-chlorine-2-aryl acetylene based on the copper (II) composite chlorinating agent. The structural formula of the copper (II) composite chlorinating agent is CuCl2.xNaCl.yAl2O3. The chlorinating agent is applicable to chlorination of various substituted aryl acetylene substrates, and is high in universality; the chlorinating agent can directly carry out chlorination reaction on aryl acetylene so as to obtain a 1-chlorine-2-aryl acetylene product; the method is mild in reaction condition, 1-chlorine-2-aryl acetylene can be synthesized with high yield and high selectivity, and the production cost of the 1-chlorine-2-aryl acetylene derivative is greatly lowered.

Synthesis of 1-chloroalkynes from alkynylsilanes using trichloroisocyanuric acid as chlorinating agent

A new method is reported for preparing 1-chloroalkynes from alkynylsilanes using trichloroisocyanuric acid (TCCA) as chlorinating agent and AgNO 3 for in situ desilylation. The method is selective for trimethylsilyl-protected alkynes relative t
