B(HSO 4 ) 3 foi facilmente preparado e usado como um novo e eficiente catalisador ácido sólido, para conversão de epóxidos às correspondentes tiocianohidrinas sob condições livre de solvente, com altos rendimentos. As principais características desta metodologia são o baixo custo do processo, a facilidade de obtenção do catalisador, a versatilidade e alta regiosseletividade do procedimento.B(HSO 4 ) 3 was easily prepared and used as a novel and efficient solid acid catalyst for conversion of epoxides to the corresponding thiocyanohydrins under solvent-free conditions with high isolated yields.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
