Crystal structure resolution of two different chlorhexidine salts
(2016-10-05) - Journal article
Two salts of the chlorhexidine di-cation (H2CHx2+) – (H2CHx)(SO4)·3H2O and (H2CHx)(CO3)·4H2O – have been synthesised and characterised crystallographically.
Enantioselective synthesis of 3,5,6-substituted dihydropyranones and dihydropyridinones using isothiourea-mediated catalysis
(2016-02-04) - Journal article
The scope of dihydropyranone and dihydropyridinone products accessible by isothiourea-catalysed processes has been expanded and explored through the use of 2-N-tosyliminoacrylates and 2-aroylacrylates in a Michael ...
Quinidine-Catalysed Enantioselective Synthesis of 6- and 4-Trifluoromethyl-Substituted Dihydropyrans
(2016-07) - Journal article
The cinchona alkaloid-catalysed enantioselective formal [4+2] cycloaddition of ethyl 2,3-butadienoate with a range of 1,1,1-trifluoro- and 4,4,4-trifluorobutenones is investigated for the preparation of stereodefined 6- ...
Spontaneous dehydrocoupling in peri-substituted phosphine-borane adducts
(2016-02-07) - Journal article
Bis(borane) adducts Acenap(PiPr2·BH3)(PRH·BH3) (Acenap = acenaphthene-5,6-diyl; 4a, R = Ph; 4b, R = ferrocenyl, Fc; 4c, R = H) were synthesised by the reaction of excess H3B·SMe2 with either phosphino-phosphonium salts ...
Neutral iodotriazoles as scaffolds for stable halogen-bonded assemblies in solution
(2016-10-01) - Journal article
The halogen bond (XB) donor properties of neutral 1,4-diaryl-5-iodo-1,2,3-triazoles, are explored using a combination of computational and experimental results and are shown to be competitive in halogen bonding efficiency ...
Solution-processable silicon phthalocyanines in electroluminescent and photovoltaic devices
(2016-04-13) - Journal article
Phthalocyanines and their main group and metal complexes are important classes of organic semiconductor materials, but are usually highly insoluble so frequently need to be processed by vacuum deposition in devices. We ...
Fluorine in fragrances : exploring the difluoromethylene (CF2) group as a conformational constraint in macrocyclic musk lactones
(2016-01-07) - Journal article
The CF2 group is incorporated into specific positions within the lactone ring of the natural musk lactone, (12R)-(+)-12-methyl-13-tridecanolide, a constituent of Angelica root oil, Angelica archangelica L. The approach is ...
Enhancing the photoluminescence quantum yields of blue-emitting cationic iridium(III) complexes bearing bisphosphine ligands
(2016-02-01) - Journal article
Herein we present a structure-property relationship study of thirteen cationic iridium (III) complexes of the form of [Ir(C^N)2(P^P)]PF6 in both solution and the solid state through systematic evaluation of six bisphosphine ...
