The elements bromine and fluorine, or iodine and fluorine, can be added to fluoroalkenes by treating the alkene with a mixture of bromine trifluoride and bromine, or iodine pentafluoride and iodine (Equations (10)–(22)). Here, ‘IF’ refers to a stoichiometric mixture of iodine pentafluoride...
Alkynylsulfides(369) have also been used as starting materials. For example, the derivatives (369; R=S-p-Tol,S-p-NO6C6H4, R1=p-Tol,p-NO2C6H4) react with bromine in chloroform to give thedibromides(370) presumably as the (E) isomers but the yield was not stated, whilst, in a ...
