11. This humble attitude was a rejection of any patronizing functionalization of the reconciliation thought process. 12. By potentially omitting them, there is potential for a more complex pattern of functionalization . 13. The thiol-ene functionalization of surface has widespread applications in material science and biotechnology. 14. This is a useful method for further functionalization of the generally less reactive 3-position. 15. An easy functionalization of the inner surface opens a wide field of applications for porous glasses. 16. The direct oxidative functionalization of C-H bonds is an ongoing problem in oxidation chemistry. 17. After reaction with a 9-BBN ), subsequent functionalization can result in hydroxyl functionalities. 18. Other methods of functionalization include enzymatically inserting azides into proteins, and synthesizing phospholipids conjugated to cyclooctynes. 19. Racemic threonine can be prepared from crotonic acid by alpha-functionalization using mercury ( II ) acetate. 20. Free radical polymerization has uses in research as well, such as in the functionalization of carbon nanotubes.
