Aryl- A nd heteroaryl-dichlorophosphines are mildly and selectively made in a one-pot synthesis in moderate to good yields starting from the respective aryl bromides or five-membered heterocycles, following lithiation with nBuLi, transmetalation with ZnCl
Chemo-, Regio-, and Enantioselective Rhodium-Catalyzed Allylation of Triazoles with Internal Alkynes and Terminal Allenes
Berthold, Dino,Breit, Bernhard
supporting information, p. 598 - 601 (2018/02/10)
The rhodium-catalyzed asymmetric N1-selective and regioselective coupling of triazole derivatives with internal alkynes and terminal allenes gives access to secondary and tertiary allylic triazoles in very good enantioselectivities. For this process, three new members of the JosPOphos ligand family have been prepared and employed in catalysis. The optimized reaction conditions enable the coupling of triazoles with internal alkynes as well as with allenes, displaying a high tolerance for functional groups. A gram scale reaction provided N1-allyltriazole, which was subjected to various transformations highlighting synthetic utility.
Rhodium-catalyzed dehydrocoupling of fluorinated phosphine-borane adducts: Synthesis, characterization, and properties of cyclic and polymeric phosphinoboranes with electron-withdrawing substituents at phosphorus
Clark, Timothy J.,Rodezno, Jose M.,Clendenning, Scott B.,Aouba, Stephane,Brodersen, Peter M.,Lough, Alan J.,Ruda, Harry E.,Manners, Ian

The dehydrocoupling of the fluorinated secondary phosphine-borane adduct R2PH·BH3 (R = p-CF3C6H 4) at 60°C is catalyzed by the rhodium complex [{Rh(μ-Cl)(1,5-cod)}2] to give the four-membered chain R
