Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1608-26-0, Name is Tris(dimethylamino)phosphine
, COA of Formula: P[N(CH3)2]3.
Highly enantioselective cationic iridium-catalyzed hydroarylation of bicycloalkenes, by carbonyl-directed C-H bond cleavage, was accomplished using a newly synthesized sulfur-linked bis(phosphoramidite) ligand (S-Me-BIPAM). The reaction provides alkylated acetophenone or benzamide derivatives in moderate to excellent yields and good to excellent enantioselectivities. Notably, the hydroarylation reaction of 2-norbornene with N,N-dialkylbenzamide proceeds with excellent enantioselectivity (up to 99% ee) and high selectivity for the mono-ortho-alkylation product. Linked up: Asymmetric intermolecular hydroarylation of bicycloalkenes by C-H bond cleavage has been developed. The use of a chiral sulfur-linked bis(phosphoramidite) ligand (L) led to excellent enantioselectivity. Notably, the hydroarylation of 2-norbornene with N,N-dialkylbenzamide proceeds with high selectivity for the mono-ortho-alkylation product. DCE=1,2-dichloroethane.
