Branch-selective, Iridium-catalyzed hydroarylation of monosubstituted alkenes via a cooperative destabilization strategy

Highly branch-selective, carbonyl-directed hydroarylations of monosubstituted alkenes are described. The chemistry relies upon a cationic Ir(I) catalyst modified with an electron deficient, wide bite angle bisphosphine ligand. This work provides a regioisomeric alternative to the Murai hydroarylation protocol.

A new method for the synthesis of dichlorophosphines

A new method for the synthesis of alkyldichlorophosphines by chlorination of alkylphosphines with phosphorus pentachloride under mild conditions is described.

Preparation of polyfunctional phosphines using zinc organometallics

The reaction of functionalized diorganozincs with chlorodiorganophosphines provides polyfunctional phosphines in good yields. Especially attractive is the hydroboration/boron-zinc exchange sequence which allows the conversion of functionalized olefins into polyfunctional phosphines in a one-pot procedure. Several new chiral phosphines have been prepared starting from readily available chiral olefins (terpenes) and their efficiency in asymmetric hydrogenation reactions has been evaluated.

Bifunctional aminophosphanes (Et2N)2P-n-P(NEt2)2 (n = 1-10) (1) and Et2NP(R)-n-P(R)NEt2 (n = 2-4, R = Alkyl, Ph) (2), which are valuable intermediates in organophosphorus synthesis, are obtained by two methods.Because of the marked nucleophility of phosphorus in 1 and 2, reactions with Lewis acids take place very smoothly as is shown by preparation of (Et2N)2P(X)-4-(X)P(NEt2)2 (X = O, S, Se, Te, BH3, BBr3) and 4-(CH3)P(NEt2)2>2+2I-.Fission of P-N bonds by PCl3, MeOH, H2S and CS2 affords Cl2P-4-PCl2, (MeO)2P-4-P(OMe)2, (MeO)Et2NP-4-PNEt2(OMe), the dithiophosphinate 4-(H)PS2>2-2 Et2NH2+, and the dithiocarbaminate 2P-4-P2.The 31P/1H/NMR-Spectra are discussed especially with regard to steric aspects in the synthesis of the chiral compounds 2 and their derivatives.
