A nickel-catalyzed aryl thioether metathesis has been developed to access high-value thioethers. 1,2-Bis(dicyclohexylphosphino)ethane (dcype) is essential to promote this highly functional-group-tolerant reaction. Furthermore, synthetically challenging macrocycles could be obtained in good yield in an unusual example of ring-closingmetathesis that does not involve alkene bonds. In-depth organometallic

A new class of non-mesomerically stabilized, unbranched, configurationally stable lithiated α-thiocarbanion has been synthesized and its stereospecific reactions with several electrophiles were investigated.
