Multicomponent Reactions with Isocyanides.
Alexander Dömling,Ivar Ugi +1 more
TL;DR: MCRs and especially MCRs with isocyanides offer many opportunities to attain new reactions and basic structures, however, this requires that the chemist learns the "language" of M CRs, something that this review wishes to stimulate.

A short history of ionic liquids—from molten salts to neoteric solvents
TL;DR: Ionic liquids, defined here as salts with melting temperatures below 100 °C, evolved from traditional high temperature molten salts and were observed as far back as the mid 19th century.
