The article focuses on photocalysis as a tool to reduce the use of hazardous substances in producing carbon-carbon bond. The photochemical activation eliminates the residue obtained from the toxic or polluting reagents.The potential impact of photocalyzed and thermal reactions indicates that the forme...
