heterolytic in a sentence

1. this is due to heterolytic fission of the Br–F bond, leading to rapid electrophilic bromination by Br. At room temperature, bromine trifluoride (BrF3) is a straw-coloured liquid.

2. and (iii) whose preferred mode of dissociation in the gas phase (or low ε inert solvent) is heterolytic rather than homolytic.

3. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs.

4. Thus C–X is broken by heterolytic fission resulting in a halide ion, X. As can be seen, the OH is now attached to the alkyl group, creating an alcohol.

5. Once formed, the Fe(II)-O-O-BH4 bridge is broken through heterolytic cleavage of the O-O bond to Fe(IV)=O and 4a-hydroxytetrahydrobiopterin;

6. In chemistry, a leaving group is a molecular fragment that departs with a pair of electrons in heterolytic bond cleavage.

7. Heterolytic O-O bond cleavage then affords a high-valent iron (IV) oxo intermediate (C), which transfers the second oxygen to sulfur.

8. During heterolytic bond cleavage of a neutral molecule, a cation and an anion will be generated.

9. Heterolytic fission almost always happens to single bonds, the process usually produces two fragment species.

10. For the anionic case, excitation of a metal center is followed by either heterolytic bond cleavage or electron transfer generating the active anionic initiator.

11. It can result from the heterolytic breaking of covalent bonds.

12. While newer polymers can yield in other ways, traditional polymers typically yield through homolytic or heterolytic bond cleavage.

13. Polymers have also been observed to undergo heterolytic bond cleavage through isotope labeling experiments.

14. Two groups have independently proposed a heterolytic fragmentation mechanism.

15. In general, there are two classifications for bond cleavage: homolytic and heterolytic, depending on the nature of the process.

16. The triplet and singlet excitation energies of a sigma bond can be used to determine if a bond will follow the homolytic or heterolytic pathway.

17. In heterolytic cleavage, or heterolysis, the bond breaks in such a fashion that the originally-shared pair of electrons remain with one of the fragments.

18. For example, an epoxide ring can be opened by heterolytic cleavage of one of the polar carbon–oxygen bonds to give a single acyclic structure.

19. This hydricity can be measured by heterolytic cleaving hydrogen between a metal complex and base with a known pKa then measuring the resulting equilibrium.

20. This reaction is defined as a heterolytic cleavage since a pair of electrons is transferred.

21. For alcohols, this heterolytic cleavage releases a water molecule.

22. These processes are known as homolytic cleavage and heterolytic cleavage.

23. Heterolytic bond cleavage is a process where the electron pair that comprised a bond moves to one of the atoms that was formerly joined by a bond.

24. In the scheme shown, the E- and Z-vinyl triflates form after heterolytic carbon-iodine bond cleavage and subsequent trapping of the cation by triflate.

25. The figure to the right depicts photochemical solvolysis of vinyl iodonium salt, through heterolytic carbon-iodine bond cleavage, to generate a vinyl carbocation and iodobenzene.

26. This can take place by a process of homolytic cleavage/ homolysis or heterolytic cleavage/ heterolysis of the bond.

27. This term is also called inductive cleavage and is an example of heterolytic bond cleavage.

28. Heterolytic fragmentation is bond cleavage where the bonding electrons remain with only one of the fragment species.

29. Important side reactions include heterolytic cleavage, in which the homoallylic alcohol decomposes into a carbonyl and an allylic system.

30. For example, aryl halide and alkyl halide can be differentiated by the reactivity trends of two electrophiles whether it prefers heterolytic or hemolytic pathway.
