摘要:
An effective, economic and green synthesis of carboxylic group substituted alkynes by Sonogashira coupling of halogenated aromatic acids with phenylacetylene has been developed. The coupling reaction proceeds well using Pd(OAc)(2)/TPPTS-CuI as catalyst with K2CO3 as base in water. It is worth noting that this procedure avoids the protection/deprotection steps of carboxylic group and obtains the title compounds in good to excellent yields.
