Investigations in the field of oxygen-containing heterocycles
In the presence of stannic chloride, 2,3-dichlorotetrahydrofuran adds to isoprene with the formation of 3-chloro-2-(4′-chloro-2′-methylbut-2′-enyl)tetrahydrofuran and to piperylene and bivinyl with the formation, predominantly, of 3-chloro-2-(4′-chloropent-2′-enyl)- and 3-chloro-2′-(4′-chlorobut-2′-enyl)tetrahydrofuran, respectively, with their allyl isomers. The amount of the latter was estimated from the NMR spectra at 20–30%.
