Calcium carbide and its recent advances in biomass conversion

Calcium carbide(CaC_(2))is a sustainable source of acetylene which plays an important role in organic synthesis due to its active triple bonds and terminal protons.Solid CaC_(2) has several advantages over acetylene gas such as easy handling,convenient storage and transportation.The CaC_(2) is considered as a safer and more convenient source of acetylene.The chemistry of the CaC_(2) is not confined to its use as a source of acetylene and its applications are not limited to the known reactions of acetylene.With the CaC_(2) chemistry being actively developing recently,it may eventually lead to the development of new transformations of alkyne chemistry.Herein,this mini review is focused on the synthesis and application of the CaC_(2) in biomass transformations.
