A Comparsion between Zeolite-Solvent Slurry and Dry Solid Photolyses

The use of zeolite-solvent slurry as a convenient medium to carry out photoreactions is illustrated with four examples, namely Norrish type I reaction of dibenzyl ketones, Norrish type I and type II reactions of α-alkylbenzyl benzyl ketones, Norrish type II reaction of aryl alkyl ketones, and photodimerization of acenaphthylene.Solvent present within the supercages of zeolites X and Y provides constraint on the mobility of the included guest molecules.Such restrictions are reflected in the product distributions.The difference in the product distribution obtained between the zeolite-solvent slurry and a homogeneous solution is often higher than that between the dry powder zeolites and a homogeneous solution.
Norrish Type I and Type II Reactions of Ketones as Photochemical Probes of the Interior of Zeolites

The Norrish type I and type II reactions of alkylbenzoin ethers, alkyldeoxybenzoins and α-alkyldibenzyl ketones included within the microporous structures of zeolites X and Y have been investigated.Product distributions varied significantly from that observed in benzene.In addition, it differed between various alkali-metal cation-exchanged samples.These variations are interpreted to result from the restriction offered by the zeolite micropores on the motions of the adsorbed organic molecule.Although this study is restricted to ketones, the knowledge gained is expected to be of general value.
MODIFICATION OF PHOTOCHEMICAL REACTIVITY BY ZEOLITES: ROLE OF CATIONS IN CONTROLLING THE BEHAVIOR OF RADICALS GENERATED WITHIN FAUJASITES.

α-Alkyldibenzylketones included in cation exchanged faujasite type zeolites show photobehavior different from that in isotropic organic solvents.Rearrangement and disproportionation which do not contribute in solution are the major processes within the cavities of faujasites.Cation size plays a major role in controlling the pathway pursued by the primary and the secondary radical pair.
Synthesis and Mesomorphic Properties of 2,6-Disubstituted Tetralins
Cereghetti, Marco,Marbet, Roman,Schleich, Kuno
, p. 1318 - 1330 (2007/10/02)
Synthesis and mesomorphic behavior of nine members of each of the two classes of 6-phenyl- and 2-phenyltetralins and five members of the 2-trans-cyclohexyltetralins are reported.The synthesis of one member of each class is described in detail.Besides the target compounds, more than twenty intermediates showed liquid crystalline properties; their transition temperatures are recorded (see Tables 1-6).
