WebFeb 1, 2009 · Abstract and Figures The kinetics and mechanism of the deprotection (detritylation) of 5'-O- (4,4'-dimethoxytrityl)-2'-deoxythymidine nucleoside catalysed by dichloroacetic acid to give a... Tritylation is often employed to transiently block C-6 (ready removal under mild acid conditions). This is also the site of enzymatically catalyzed phosphorylation of glucose and other sugars, the first step in their metabolic utilization. Oxidation to a carboxylic acid is common.

WebThe tritylation reaction rates/yields achieved by light induced isomerization are compared between the native and photoswitched states of the catalyst T1. This concept of controlling the tritylation reaction rates with light has also been extended to additional substrates. http://www.orgsyn.org/demo.aspx?prep=V75P0184 the amazing race season 6 cast

The nitrites make methemoglobin, which has a greater affinity for cyanide than does the cytochrome oxidase enzymes. The combination of methemoglobin and cyanide forms cyanomethemoglobin.
