摘要:
The present invention relates to a Sonogashira-Carbonylation reaction using two types of gas, as well as novel crystals which can control a heat of the said reaction and the process of producing the same. In addition, the present invention relates to a ligand (additive) to prevent the deactivation of a palladium catalyst.
