Ozonolyses of 1,2-diphenylindene (7), 2-phenylindene (18), and the structurally related acyclic keto olefins 13, 14, 26, and 32 were conducted in MeOH/CH 2 Cl 2 at -70 and 0 o C. The structure of the indenes, 7 and 18, and the reaction temperature, w

Nucleophilic reactivity and solvation patterns for succinimidide and phthalimidide ions have been characterized through three procedures, kinetic and enthalpy of solution measurements in aceto-nitrile-methanol mixtures, and enthalpy of reaction measu

Studies of 5,10,15,20-tetrakis(4-n-alkylphenyl)porphyrins revealed that the homologues with longer alkyl chains than hexyl were mesomorphic, in contrast to the non-mesomorphic alkoxy derivatives. Metal complexes (Co, Ni, Cu, Zn, and Pd) of the dodecy

Reactions between cyclopenta-1, 3-dienes 1a–i and ozone, conducted in a variety of solvents including diethyl ether, pentane, CCl4, CH2Cl2, CF3CH2OH, AcOH, and MeOH, afforded predominantly monomeric ozonolysis products consisting of either bicyclic

Ozonolyses of the vinyl ethers 1a-f in methanol afforded almost exclusively the corresponding α-methoxy hydroperoxides 4, suggesting the preferred formation of the carbonyl oxides 2. In aprotic solvents including methyl formate, the predominant mode

The ozonolysis of vinyl ethers 1a, b in the presence of adamantane-2-thione 4a and bicyclo[3.3.1]nonan-9-thione 4b gave in each case the corresponding thioozonides 5a–c in moderate yields, whilst ozonolysis of a mixture of vinyl ethers 1a–d and t

Carbonyl oxides, derivatives by ozonolysis of vinyl ethers, readily undergo [3+3] cycloaddition reactions with nitrones affording dihydro-1,2,4,5-trioxazines in fair to excellent yield. The structures of dihydro-3,5,6-triphenyl-1,2,4,5-trioxamine (5f
