Among benzene derivatives, halogen-substituted compounds have been extensively studied and in the structure-reactivity studies " carried out on the reaction of OH and SO with the ortho and meta isomers of dichloro and dibromobenzenes and mono-bromotoluenes, the formation of substituted hydroxycyclohexadienyl radical was observed to be the major reaction channel. The bimolecular rate constants obtained for the reaction of OH with substituted halobenzenes are in the range (1.7 to 9.3) x 10 dm mol s. The rate constants obtained are found to follow the Hammett relationship for the reaction of OH with substituted halobenzenes and the p was found to be -0.5, indicating that OH radicals react by addition to the benzene ting.

Both of these complexes can be used in ADMET polymerizations at temperatures up to approximately 55 °C, although decomposition certainly occurs over the time scale of a typical ADMET polymerization (days). A structure-reactivity study was performed on complexes 1 and 2 that revealed a number of features of these complexes [68]. Notably, 2 will polymerize dienes containing a terminal and a 1,1-disubstituted olefin, but never produces a tetrasubstituted olefin. One of the substituents of the 1,1-disubstituted olefin must be a methyl group. In contrast, complex 1 will not react with a 1,1-disubstituted olefin. The tungsten complex is more reactive towards internal olefins than external olefins [23, 63] indicating that secondary metathesis, or trans-metathesis, probably dominates the catalytic turnovers in ADMET with complex 1.

In a remarkable article published in 1991 [39], Bunting reviewed structure-reactivity studies relevant to the nature of the hydride-transfer process between materials that can be regarded as related to nicotinamide cofactors. Much of the article concerned the large quantity of work published from Bunting s own laboratory. 

Although the structure/reactivity studies conducted by Jencks and co-workers suggest that metaphosphate will not occur as an intermediate in aqueous reactions (54), and it is known that phosphorothioate esters undergo dissociative hydrolysis more rapidly than phosphate esters (40), Weiss and Cleland have recently utilized secondary 0 isotope effects to probe the mechanism of the hy-... 

First we describe the copolymerization of oxetanes, as an example for microstructure and structure/reactivity studies. Then we discuss the copolymerization of thietanes, azetidines and oxazolines. Finally, we show the relationship between structure of heterocyclics (basicity, ring strain) and their nucleophilic reactivity.
