Palladium-Catalyzed Difluoroalkylation of Isocyanides: Access to Difluoroalkylated Phenanthridine Derivatives

An efficient and general method for the synthesis of difluoroalkylated phenanthridine derivatives through palladium-catalyzed reaction of difluoroalkyl bromides with isocyanides is described. The reaction can also be extended to perfluoroalkyl iodides. Mechanistic studies reveal that a difluoroalkyl radical via a single-electron-transfer pathway is involved in the reaction.

Bis(perfluoroalkyl) phosphino-oxazoline: A modular, stable, strongly pi-accepting ligand for asymmetric catalysis

A new class of stable, strongly pi-accepting and modular bis-(perfluoroalkyl)-phosphine-oxazoline ligands (FOX) as CO mimics was prepared. It was demonstrated that these ligands, when coordinated to palladium catalysts, promote the asymmetric alkylation of monosubstituted allyl substrates with excellent regio- and enantioselectivity. Solid and solution structure analysis of the FOX-ligated Pd-allyl intermediate reveals that the combination of relative steric and strong trans influences presented by the P(CF 3)2 moiety gave rise to the excellent selectivity.

Palladium/nickel-cocatalyzed cycloaddition of 1,3-dehydro-o-carborane with alkynes. Facile synthesis of C,B-substituted carboranes

o-Carboryne (1,2-dehydro-o-carborane) has been reported as a very reactive intermediate and regarded as a three-dimensional relative of benzyne, whereas the 1,3-dehydro-o-carborane has remained elusive. In this article, we present the preparation of 1,3-dehydro-o-carborane from 3-iodo-1-lithio-o-carborane mediated by palladium(0). This reactive intermediate can be trapped by alkynes via Pd/Ni-cocatalyzed [2 + 2 + 2] cycloaddition reaction, leading to the formation of C,B-substituted-o-carborane derivatives. The possible reaction mechanism involving the formation of metal-1,3-dehydro-o-carborane followed by stepwise insertions of 2 equiv of alkyne and reductive elimination is proposed, and the relative reactivity of M-C versus M-B bond in metal-1,3-dehydro-o- carborane complexes is also discussed. This work offers a new methodology for B-functionalization of carboranes and demonstrates that metal-1,3-dehydro-o- carborane can be viewed as a new kind of boron nucleophile.

Linear and V-Shaped Alkynyl-1,3,5-triazines

A concise route for the synthesis of linear and V-shaped alkynyl-1,3,5-triazines has been developed by starting from 2,4-dichloro-1,3,5-triazine derivatives. The sequential substitution of the 2- and 4-chloro groups by a regioselective Sonogashira coupling reaction afforded symmetric and unsymmetric V-shaped alkynyl-1,3,5-triazines. A modulated copper-free Pd/1,10-phenanthroline catalyst system showed good compatibility with the -OCH3, -NPh2, and p-CH3OC6H4- substitutents and furnished the targeted linear alkynyl-1,3,5-triazines in good yields. A Pd/Ag bimetallic system afforded the desired symmetric and unsymmetric V-shaped alkynyl-1,3,5-triazines in moderate to good yields. The photophysical properties of the new alkynyl-1,3,5-triazine compounds were characterized experimentally. The X-ray diffraction analysis of 2a confirmed a coplanar position between the phenyl group and the 1,3,5-triazinal moiety. Intermolecular pi-pi interactions were observed between two of the TZ units, and the shortest atomic contact distance between the phenyl moieties of two adjacent molecules is 3.655 A. A protocol has been developed for the synthesis of alkynyl-1,3,5-triazines, especially unsymmetrical alkynyl-1,3,5-triazines with two different alkynyl groups on the triazine core. The Pd2(dba)3/1,10-phenanthroline catalyst system was used in a copper-free Sonogashira coupling reaction followed using a Pd/Ag bimetallic system for the subsequent alkynyl coupling step. dba = dibenzylideneacetone, 1,10-phen = 1,10-phenanthroline, DIPEA = N,N-diisopropylethylamine, and Tf = trifluoromethylsulfonyl.
