Reaction of the bis-9-BBN adduct of several dienes with 1,3-dibromobenzene via Suzuki coupling leads to a series of [n]metacyclophanes ranging in size from 10 to 17 atom members. In each case, two carbon-carbon bonds are formed in one reaction vessel. However, when the bis-9-BBN adduct of 1,5-hexadiene is coupled with a variety of aryl dihalides, larger [n.n]cyclophanes were formed in preference to the [n]cyclophanes. Four carbon-carbon bonds are formed in this instance. Single-crystal X-ray analyses of these [n.n]cyclophanes reveal interestingly shaped molecules with large cavities.

The synthesis and initial study of a new series of eneyne-bridged cyclophanes (revolveneynes) are described in which the phenyl rings are free to rotate within the cavity. Either palladium coupling or oxidative dimerization provided rapid access to [14],

Cyclic diketo sulfides 4 (n=3-8, 10) were condensed with glyoxal to give thiophenophanediones 6.The NMR, IR and UV spectral data of 6 are consistent with the following picture.The thiophene-2,5-dicarbonyl moiety in 6 (n=10) is in the mean molecular plane
A 1,10-HOFMANN ELIMINATION. SYNTHESIS OF A PARACYCLOPHANE TETRAENE
