Arenediazonium tetrafluoroborates reacted with 3-chloro-2-methylpropene in the presence of potassium chloride, bromide, and thiocyanate to give the corresponding 1-aryl-3-chloro-2-halo(thiocyanato)-2-methylpropanes. The presence of a copper salt is a necessary condition for the reaction to occur. The yields of the corresponding 1-aryl-3-chloro-2-halo-2-methylpropanes in the Meerwein reaction were approximately twice as low. Introduction of a methyl group to C2 in the 3-chloropropene molecule does not change the reaction regioselectivity.

Meerwein reactions of arenediazonium bromides with methyl and ethyl acrylates gave 3-aryl-2-bromopropionic acid esters which were subjected to cyclocondensation with N-(2-pyridyl)- and N-(6-methyl-2-pyridyl) thioureas to obtain 5-R1-benzyl-2-(R2-2-pyridylimino)thiazolidin-4-ones. The latter were shown to exist in solution as E isomers of the imino form.
