Design, synthesis, and testing of novel organic oligomers for use as molecular-scale electronic devices
… a silicon hydride passivated surface followed by diazotization of the terminal aniline. Organic aryltriazenes have been shown to assemble on hydride passivated silicon surfaces by using an in situ diazotization protocol in dilute HF solution. Film thicknesses range from a monolayer to 200 nm …

Stereoselective and Economical Methods for Chemical Synthesis of Essential Medicines
… the chemical laboratory is presented. Chapter 1: Diazotization of S-Sulfonyl-Cysteines. We report the synthesis of enantiomerically enriched 𝛽-thio-𝛼-hydroxy and 𝛼-chloro carboxylic acid and ester building blocks by diazotization of S-sulfonyl-cysteines. Within these pharmaceuticallyrelevant …

Bioactivation of diacetyldapsone in cultured lung cells
… was initially monitored by the Bratton-Marshall diazotization technique. </p> <p>Only incubation with 0.01% DADDS in 1% CD showed a significant time dependent hydrolysis of DADDS over a period of 72 hours due to insensitivity of the assay method. Over the same period, cultured lung cells produced …
