| 11. | This is suitable for cleaving glycols and alpha-hydroxy ketones in ring opening and Mannich reaction.
|
| 12. | This is because the carbocationic intermidate is delocalised onto many different carbons through a reversible ring opening.
|
| 13. | If the ring opening uses a conrotatory process then the reaction results with the HOMO of butadiene.
|
| 14. | Cyclopropylmethyl radical undergoes a very rapid ring opening rearrangement that relieves the ring strain and is enthalpically favorable.
|
| 15. | The first step involves a photochemically induced conrotatory ring opening of 7-dehydrocholesterol to form pre vitamin D3.
|
| 16. | Isotopic labeling studies indicated that the ring opening occurs via an addition elimination reaction with water addition shown below.
|
| 17. | The principle application of the fast-initiating catalysts is as initiators for ring opening metathesis polymerisation ( ROMP ).
|
| 18. | While it proceeds through an intermediate bicycle the final cyclization and ring opening take place within the same radical reaction.
|
| 19. | The polymerization process it a cationic chain growth, which takes place by ring opening polymerization of the epoxide groups.
|
| 20. | This was extended to large-molecular-size and " hypercondensed " hydrocarbons, ring opening and partial hydrogenation.
