Wang, Chang; Fan, Xiaodong; Chen, Fan; Qian, Peng-Cheng; Cheng, Jiang published an article in 2021. The article was titled 《Vinylene carbonate: beyond the ethyne surrogate in rhodium-catalyzed annulation with amidines toward 4-methylquinazolines》, and you may find the article in Chemical Communications (Cambridge, United Kingdom).Recommanded Product: Vinylene carbonate The information in the text is summarized as follows:
In this paper, a rhodium-catalyzed annulation of vinylene carbonate with amidines RNHC(=NH)R1 (R = 2-chlorophenyl, 4-tert-butylphenyl, naphthalen-1-yl, etc.; R1 = t-Bu, cyclopropyl, thiophen-2-yl, naphthalen-1-yl, etc.), leading to 4-methylquinazolines I (R2 = H, Me, F, t-Bu, etc.; R3 = H, Cl; R4 = H, Cl; R3R4 = -CH=CHCH=CH-) with moderate to excellent yields have been developed. This procedure proceeded by sequential ortho-acylation and annulation, where vinylene carbonate served as the acetylation reagent rather than the ethyne surrogate. In addition to this study using Vinylene carbonate, there are many other studies that have used Vinylene carbonate(cas: 872-36-6Recommanded Product: Vinylene carbonate) was used in this study.
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Recommanded Product: Vinylene carbonate
