"Reaction of Straiend Molecule: Hot Molecule Reactions of Cyclophane Derivatives"

Tomoyuki Yatsuhashi, Yuriko Hosoi, Seiji Shimizu, Yoshiteru Sakata, Nobuaki Nakashima

(Sapporo, Sep 24-27)

The bond dissociations of cyclophane derivatives with an ArF excimer laser were explained in terms of a multiphoton reaction of hot molecules. A slow rise of xylylene that originated in the single photon dissociation process of hot cyclophane was observed in the case of methylsubstituted paracyclophanes under low pressure conditions. The specific reaction rates of the dissociations of highly strained paracyclophanes were discussed.

"Hot Molecule Reactions of Strained Benzocycloalkenes"

Tomoyuki Yatsuhashi, Nobuaki Nakashima

(Konan Univ. Mar 28-31)

Strained alicyclic compounds: benzocyclobutene, indan, and tetralin were photolyzed by an ArF laser in the gas phase. The reactions were well explained in terms of hot molecule mechanism. The C-C bond dissociation reactions on strained alicyclic ring were explained by statistical reaction theory.
