It reviews the domain of a solvent very often quoted as the greenest or best solvent in green chemistry textbooks, namely, no solvent or solventless conditions. DCM is often used in ruthenium-catalyzed metathesis reactions as it is in general a good catalyst solvent. Recently, ring closing metathesis (RCM) of diethyl diallylmalonate (DEDAM) and cross metathesis of allylbenzene with cis-1,4-diacetoxy-2-butene were studied, both under solvent-free conditions and in methyl decanoate, a renewable and environmentally benign solvent derived from fatty acid derivatives. More recently, the synthesis of nitrogen containing heterocycles by ruthenium catalyzed RCM using low catalyst loading was studied by Grubbs. %G English %L hal-01114569 %U https://univ-rennes.hal.science/hal-01114569 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR_OMC2012 %~ ISCR-OMC %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ UR1-SDLMJONCH %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ UR1-MMS %~ TEST2-HALCNRS
