Base-catalysed additions of alcohols to F-2-butyne (1) give mainly products of -addition while -addition predominates in uncatalysed additions of alcohols carried out in a diluent. The stereochemistry of addition of diethylamine is very dependent on the solvent used and - or -addition may predominate. Stepwise and concerted mechanisms are advanced to account for these observations. Nucleophilicaddition of sulphur
