Preparation of [2.2]-para-, meta-, and ortho-cyclophanes containing a 1,3-cyclohexano group
Abstract
[2.2]-para-, meta-, and ortho-Cyclophanes containing a 1,3-cyclohexane ring bridged with two carbons were prepared through a coupling reaction to form dithiacyclophane, followed by oxidation to yield the sulfone and then pyrolysis.
