Implementation of the reaction is simple, healthy and environmentally friendly owing to the use of a non-toxic catalyst coupled to a solvent-free procedure. A large variety of known or novel compounds have thus been prepared, including with substrates bearing acid or base-sensitive functional groups %G English %2 https://univ-rennes.hal.science/hal-01174893/document %2 https://univ-rennes.hal.science/hal-01174893/file/molecules-20-11617.pdf %L hal-01174893 %U https://univ-rennes.hal.science/hal-01174893 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-MONTPELLIER %~ ENSC-RENNES %~ ICG %~ ISCR %~ SCR_ICMV %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ ISCR-CORINT %~ UR1-SDLM %~ UR1-SDLMJONCH %~ CHIMIE %~ UNIV-MONTPELLIER %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ ISCR-CORINT1 %~ UR1-MMS %~ UM-2015-2021 %~ TEST2-HALCNRS
