Pyrolysis of the relatively stable, solid complexes of cyclomaltoheptaose (β-cyclodextrin) with phenyldiazomethane, 1-diazo-1-phenylethane, and diazo-(diphenyl)methane results in degradation of the labile guests. The host matrix exerts “reaction-vessel” and “shape-selectivity” effects upon the reaction pathways of the guests and derivatives. The carbene insertion reaction with the β-cyclodextrin hydroxyl groups

Nickel (0) catalysed co-oligomerization of butadiene with heterodienes and hetero-olefins is described. It is shown how the selectivity of these reactions can be controlled by the position of the heteroatom in the heteropartner and also by the nature of the catalytic system used.

9-Fluorenethione S-p-toluenesulfonimide reacted as a 1,3-dipole with imines, oximes, and thiones to form (3+2)cycloadducts, while with symmetrical azines and aldehydes, unsymmetrical azines, N-(p-tolylsulfonyl) imines and fluorenone were obtained as a result of the decomposition of the cycloadducts.
