《Tandem Phospha-Michael Addition/N-Acylation/ Intramolecular Wittig Reaction of aza-o-Quinone Methides: Approaches to 2,3-Disubstituted Indoles》 was written by Hua, Ting-Bi; Chao, Fei; Wang, Long; Yan, Chen-Yang; Xiao, Cong; Yang, Qing-Qing; Xiao, Wen-Jing. Recommanded Product: Ethyl oxalyl monochloride And the article was included in Advanced Synthesis & Catalysis in 2020. The article conveys some information:
A tandem phospha-Michael addition/N-acylation/intramol. Wittig reaction of in situ formed aza-o-QMs is disclosed. This approach features high functional group tolerance and provides a convenient and practical access to biol. significant indole derivatives (37 examples, up to 91% yield) under mild reaction conditions. In the part of experimental materials, we found many familiar compounds, such as Ethyl oxalyl monochloride(cas: 4755-77-5Recommanded Product: Ethyl oxalyl monochloride)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Recommanded Product: Ethyl oxalyl monochloride
