TRANSFORMATIONS OF HALOCYCLOPROPANES-VI. REACTIONS OF 7,7-DICHLOROBICYCLOHEPTANE WITH SOME ORGANIC ANIONS IN NONPOLAR MEDIA

Arct, J.,Migaj, B.

, p. 953 - 956 (2007/10/02)

The reactions of 7,7-dichlorobicyclo-heptane, 1 with organic bases were carried out in benzene and THF.The reaction course of 1 in nonpolar media is different from that in DMSO; the rearrangements of cyclopropene 3 taking place in the former. 8 is produced by the shift of double bond into the C6 ring.The cyclopropene-carbene isomerization and reactions of carbenes 14 and 15 with alkoxide anions are the probable route leading to the other products.
