5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Product Details of 1186603-47-3

A concise synthesis of 10-benzoyl-3,4-dihydroanthracen-1(2H)-one derivatives catalyzed by TfOH under metal-free conditions was written by Wu, Hao;Chen, Hua-Dong;Liu, Jian-Quan;Li, Qiu-Yan;Wang, Xiang-Shan. And the article was included in Synthetic Communications in 2021.Product Details of 1186603-47-3 The following contents are mentioned in the article:

TfOH was proved to be an efficient catalyst to promote the intra-mol. cyclization, Diels-Alder reaction, deprotonation and dehydration and provided a synthesis of 10-benzoyl-3,4-dihydroanthracen-1(2H)-ones I [R = Ph, 4-FC6H4, 4-EtC6H4, etc.; R1 = H, 7-F, 6-Cl, etc.; R2 = H; R3 = Ph; R2 = R3 = Me; R4 = H, Me] in good yields from a reaction of 2-(phenylethynyl) benzaldehyde and cyclohexane-1,3-dione. It underwent in high regioselectivity when center asym. 4,4-dimethylcyclohexane-1,3-dione was used as a reactant. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3Product Details of 1186603-47-3).
