Geometrically enforced donor-facilitated dehydrocoupling leading to an isolable arsanylidine-phosphorane
(2014-04) - Journal article
A proximate Lewis basic group facilitates the mild dehydrogenative P–As intramolecular coupling in the phosphine-arsine peri-substituted acenaphthene 3, affording thermally and hydrolytically stable arsanylidine-phosphorane ...
A structural, spectroscopic and computational examination of the dative interaction in constrained phosphine–stibines and phosphine–stiboranes
(2015-05-11) - Journal article
A series of phosphine–stibine and phosphine–stiborane peri–substituted acenaphthenes containing all permutations of pentavalent groups –SbClnPh4-n (5–9), as well as trivalent groups –SbCl2, –Sb(R)Cl, and –SbPh2 (2–4, R = ...
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 ...
Geminally substituted tris(acenaphthyl) and bis(acenaphthyl) arsines, stibines and bismuthine : a structural and Nuclear Magnetic Resonance investigation
(2016-07-18) - Journal article
Tris(acenaphthyl) and bis(acenaphthyl) substituted pnictogens (iPr2P-Ace)3E ( 2 – 4 ) (E = As, Sb, Bi; Ace = acenaphthene-5,6-diyl) and (iPr2P-Ace)2EPh ( 5 and 6 ), (E = As, Sb) were synthesised and fully characterised by ...
Reactivity profile of a peri-substitution-stabilized phosphanylidene-phosphorane : synthetic, structural, and computational studies
(2014-06-09) - Journal article
The reactions of peri-substitution-stabilized phosphanylidene-phosphorane 1 with [AuCl(tht)] or [PtCl2(cod)] afford binuclear complexes [((1)(AuCl)2)2] 2 and [((1)(PtCl2))2] 3, in which four electrons of the ligand are ...
Understanding a hydroformylation catalyst that produces branched aldehydes from alkyl alkenes
(2017-11-08) - Journal article
This paper reports experimental and computational studies on the mechanism of a rhodium-catalysed hydroformylation that is selective for branched aldehyde products from unbiased alkene substrates. This highly unusual ...
Weak Te,Te interactions through the looking glass of NMR spin-spin coupling
(2013) - Journal article
Across the bay: J(125Te,125Te) spin–spin coupling is a highly sensitive probe into the electronic and geometric structure of 1,8-peri-substituted naphthalene tellurium derivatives. The coupling is related to the onset of ...
Electrochemically informed synthesis : oxidation versus coordination of 5,6-Bis(phenylchalcogeno)acenaphthenes
(2013-10-07) - Journal article
Rhodium(III) and iridium(III) half-sandwich complexes with tertiary arsine and stibine ligands
(2015) - Journal article
The syntheses of rhodium(III) and iridium(III) half sandwich complexes containing tertiary arsine and stibine ligands of the form [Cp*M(L)Cl2] (M = Rh, Ir; L = AsEt3, AsPh3, SbPh3) are reported. These compounds represent ...
Sterically crowded peri-substituted naphthalene phosphines and their PV derivatives
(2010-07-05) - Journal article
Three sterically crowded peri-substituted naphthalene phosphines, Nap[PPh2][ER] (Nap=naphthalene-1,8-diyl; ER=SEt, SPh, SePh) 1–3 , which contain phosphorus and chalcogen functional groups at the peri positions have been ...
