摘要: A new synthesis of 3,4-diphenyl-4-aryl-1,2,5-thiadiazolines 1,1-dioxide through the addition of aromatic derivatives to 1,2,5-thiadiazole 1,1-dioxide is presented. Anhydrous AlCl3 is used as catalyst.关键词: n/a DOI: 10.3390/50300503 被引量: 14 ...
The addition of a β C–H bond to the formyl group of aldehydes to olefins took place with the aid of Ru(H)2(CO)(PPh3)3 as a catalyst. Several olefins can be used in the catalytic reaction of conjugate enals. The presence of a sterically hindered substituent at the ortho position of...
