A study of the oxidative cyclization of 13C-labelled bilenes-b substituted with a methyl group at one terminal position and a formyl equivalent at the other, e.g. (1), has clearly established that the methyl group provides the carbon atom to complete the ring system. The basic mechanism of this reaction is discussed.

Insight Into

ABSTRACTThis paper models maximum entropy configurations of idealized gravitational ring systems. Such configurations are of interest because systems generally evolve toward an ultimate state of maximum randomness. For simplicity, attention is confined to ultimate states for which interparticle interactions are no longer of first order importance. The planets, in their orbits about the sun, are one example of such a ring system. The extent to which the present approximation yields insight into ring systems such as Saturn's is explored briefly.
