Palladium-catalyzed tandem reaction of epoxynitriles with arylboronic acids in aqueous medium: divergent synthesis of furans and pyrroles

The efficient selective synthesis of furans and pyrroles has been realized by means of a palladium-catalyzed tandem addition/ring-opening/cyclization reaction of 2-(3-aryloxiran-2-yl)acetonitriles with arylboronic acids in aqueous medium for the first time. The chemoselectivity of this transformation can be predominantly governed by the steric effects of arylboronic acids: the reactions of 2-(3-aryloxiran-2-yl)acetonitriles with the less sterically hindered arylboronic acids provided furans as the sole products, while those of the sterically bulky arylboronic acids delivered pyrroles selectively. The O-18-labelled experiments revealed that the oxygen atom of furans is derived from water, and a plausible mechanism for this selective synthesis of furans and pyrroles was proposed.

Ru-II and Ru-III Chloronitrile Complexes: Synthesis, Reaction Chemistry, Solid State Structure, and (Spectro)Electrochemical Behavior

The synthesis of [Ti6O4(OiPr)(8)(O2CPh)(8)] (3) and [RuCl(N equivalent to CR)(5)][RuCl4(N equivalent to CR)(2)] (4a, R = Me; 4b, R = Ph), [Ru(N equivalent to CPh)(6)][RuCl4(N equivalent to CPh)(2)] (5) and [H3O][RuCl4(N equivalent to CMe)(2)] (7a) is discussed. Crystallization of 5 from CH2Cl2 gave trans-[RuCl2(N equivalent to CPh)(4)] (6). The solid-state structures of 3, 4a,b, 5, 6 and 7a are reported. Complex 4b forms a 3D network, while 6 displays a 2D structure, due to pi-interactions between the benzonitrile ligands. The (spectro)electrochemical behavior of 4a,b and 6 was studied at 25 and -72 degrees C and the results thereof are compared with [NEt4][RuCl4(N equivalent to CMe)(2)] (7b) and [RuCl(N equivalent to CPh)(5)][PF6] (8). The electrochemical response of the cation and the anion in 4a,b are independent from each other. [RuCl(N equivalent to CR)(5)](+) possesses one reversible Ru-II/Ru-III process. However, [RuCl4(N equivalent to CMe)(2)](-) was shown to be prone to ligand exchange and disproportionation upon formation of either a Ru-IV and Ru-II species at 25 degrees C, while at -72 degrees C the rapid conversion of the electrochemically formed species is hindered. In situ IR and UV/Vis/NIR studies confirmed the respective disproportionation reaction products of the aforementioned oxidation and reduction, respectively.

Diastereoselective cyclisation of N-alkenylideneamines into 3,4-dihydro–2H-pyrrol-1-ium halides

A number of new chiral 2-(alpha-bromoalkyl)pyrrolinium salts and 2-(alpha-selenoalkyl)pyrrolidines were synthesized by the halocyclisation and selenocyclisation, respectively, of N-(alkenylidene)alkylamines and subsequent reduction. These cyclisations were implemented in a diastereomeric fashion for the first time. Substrate control (starting imines possessing chirality in the N-alkyl or the N-alkenyl substituent) and reagent control (chiral organoselenenyl bromides) were applied. Asymmetric induction by stereocentres of the alkenylidene or double asymmetric induction by chiral selenenyl bromides on unsaturated imines with a chiral N-alkyl group resulted in diatereoselectivities up to 84:16.

Robust and recoverable dual cross-linking networks in pressure-sensitive adhesives

Pressure-sensitive adhesives (PSAs) demand the ability to simultaneously improve toughness and adhesion. However, these requirements of PSAs have remained a great challenge because robust and recoverable characteristics are usually contradictory properties of PSAs. Dual cross-linking networks developed by incorporating dynamic noncovalent bonds into chemical cross-linking networks have the potential to mitigate these requirements in a wide variety of applications including adhesives, hydrogels, and elastomers. Herein, a facile approach to achieve dual cross-linking networks of acrylic PSAs with excellent mechanical properties and high-adhesive performance that integrate physically cross-linked networks into chemically cross-linked networks is proposed. Diurethane acrylic monomer-pentaerythritol ethoxylate (DAM-PEEL) groups were introduced into the acrylic PSA system through photopolymerization. The PSA/DAM-PEEL dual cross-linking networks led to the development of the chemically cross-linked networks for both PSA and DAM via covalent bonds and the physically cross-linked networks between the amide groups of DAM and the hydroxyl groups of PEEL via hydrogen bonds. Consequently, the PSA/DAM-PEEL dual cross-linking networks were able to simultaneously improve the modulus and stretchability. This design strategy for developing dual cross-linking networks of materials could offer potential applications for various adhesive-related applications.
