Thermal and photochemical reactions of dihydrodiazines... Chemical evidence is presented that the ring contraction of 6-phenyl-4-(2-pyridyl)-1,4(3,4)-dihydropyrimidine occurs <em>via</em> heterolytic fission of the C(1)-C(6) bond of intermediate 1-phenyl-6-(2-pyridyl)-2,4-diazabicyclo [3.1.0]...
Studies of photolytic reactions at radio frequencies.... The photolytic reactions chosen for study involved heterolytic fission, homolytic fission, free radical decomposition and geometric rearrangement, and in each case an attempt was made to record the electrical changes occurring...
Insights into the vulcanization mechanism througha simple and facile approach to the sulfur cleavage behavior...analysis.Our studies suggest that thiyl radicals derived from the homolyticcleavage of sulfur play the dominant role in the vulcanization, whilethe heterolytic fission of sulfur cannot occur as expected becausethis reaction needs 200 °C....

Synthesis, characterization,and reactivity of fecomplexes containing cyclic diazadiphosphine ligands: the role ofthe pendant base in heterolytic cleavage of h2... Studies of H/D exchange by the complexes [1-H2]+, [2-H2]+, and [3-H2]+ carried out using H2 and D2 indicate that the relatively rapid H/D exchange observedfor [1-H2]+ and [2-H2]+ compared to [3-H2]+ is consistentwith intramolecular heterolytic cleavage of H2 mediatedby the pendant amine....
