Description acceptable. A highly chemoselective form of this process can occur via a Norrish Type II photo·isomerization in nitro·benzyls such as NVOC. Anisole and p-cresol are used to prevent damaging side reactions after acylium carbocations are produced via a form of this process that uses an SN1 reaction with TFA. It’s not related to quizbowl, but this process occurs when light is shone on PPGs. Performing a type of this process selectively at low pH relies on large steric differences, such as between (*) TIPS and DMIPS. (10[1])This process is the first step of each cycle of the phosphoramidite (10[1])method, in which the formation of a DMT (-5[1])cation yields a bright orange color. Coupling and this process alternate in solid-phase peptide synthesis, (-5[1])which usually uses piperidine to perform this process on (10[1])Fmoc. (10[1]-5[1])For 10 points, name this process exemplified by treating a silyl ether with TBAF or an acid to restore an alcohol group. ■END■ (10[2]0[5])
