Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 122-99-6, Name is 2-Phenoxyethanol, SMILES is OCCOC1=CC=CC=C1, belongs to phthalazine compound. In a document, author is Im, Jeong Kyun, introduce the new discover, Formula: https://www.ambeed.com/products/122-99-6.html.
An unprecedented N-chlorinative ring contraction of 1,2-diazines was discovered and investigated with an electrophilic chlorinating reagent, trichloroisocyanuric acid (TCICA). Through optimization and mechanistic analysis, the assisting role of n-Bu4NCl as an exogenous nucleophile was identified, and the optimized reaction conditions were applied to a range of 1,4-dimethoxyphthalazine derivatives. Also, an improvement of overall efficiency was demonstrated by the use of a labile O-silyl group. A bicyclization/ring-opening mechanism, inspired by the Favorskii rearrangement, was proposed and supported by the DFT calculations. Furthermore, the efforts on scope expansion as well as the evaluation of other electrophilic promoters revealed that the newly developed ring contraction reactivity is a unique characteristic of 1,4-dimethoxyphthalazine scaffold and TCICA.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 122-99-6 help many people in the next few years. Formula: https://www.ambeed.com/products/122-99-6.html.
