Web5 mL) the resin was shaken for 24 h. the resin was filtered and washed with dichloromethane, dimethylformamide and dichloromethane successively. Resin Cleavage To the peptidyl-trichlorotrityl resin (1.2 mmol) was added a cleavage cocktail of trifluoroaceticacid:dry dichloromethane (1:19, 10 mL). The yellow resin turned bright red. WebJan 25, 2016 · Shown below in Figure 1 are two examples of homolytic cleavage in two common classes of Type I photoinitiators: hydroxyacetophenone (HAP) and phosphineoxide (TPO) [1] Figure 1. The highlighted bond in each species undergoes homolytic cleavage upon the absorption of UV light. HAP’s usually absorb shorter wavelength UV-A radiation …
