Men and perinatal depression (2016)
Journal Article

James Costello describes his own experiences as a ‘fellow traveler in a foreign land’, supporting partners of women with perinatal depression

Conformational analysis of triphenylphosphine ligands in stereogenic monometallic complexes: Tools for predicting the preferred configuration of the triphenylphosphine rotor (2015)
Journal Article

© The Royal Society of Chemistry 2015. The extension of our simple model for predicting the propeller configuration of a triphenylphosphine ligand co-ordinated to achiral metal centres to include stereogenic metal systems is described. By considerin...

Stereoselective syntheses of substituted succinic acid derivatives of the iron chiral auxiliary [(η5-C5H5)Fe(CO)(PPh3)] (2014)
Journal Article

© 2014 Elsevier Ltd. A range of alkyl- or aryl-substituted iron succinoyl complexes, incorporating the iron chiral auxiliary [(η5-C5H5)Fe(CO)(PPh3)], were prepared in high regio- and diastereoselectivities by employing four successful strategies: (i)...

Bi(III) Catalysed O-acylative cleavage of 2,5-dimethyltetrahydrofuran: A substrate dependent borderline mechanism (2005)
Journal Article

The Bi(III) catalysed O-acylative cleavage of cis- and trans-2,5- dimethyltetrahydrofuran 4 with AcCl, BzCl or i-PrCOCl is stereochemically consistent with the operation of a concerted process (AND N), which proceeds via a stabilised carbocation or '...

Bi(III) halides as efficient catalysts for the O-acylative cleavage of tetrahydrofurans: An expeditious entry to tetralins (2005)
Journal Article

The mild (DCM/20°C), quantitative, regioselective, O-acylative cleavage of tetrahydrofurans using organic acid halides with catalytic Bi(III) halides is reported. X-ray crystallography is used to rationalise the failure of the reaction in the case of...

Conformational diastereoisomers of PPh3 coordinated to stereogenic metal centres as molecular optical switches (2001)
Journal Article

The specific rotation of (RFe,R,M)-4 switches sign upon epimerisation to (RFe,S,P)-5. X-Ray crystallographic studies suggest that inversion of the propeller configuration of the coordinated PPh3 ligand is the major contributor to the switch of specif...

Synthesis and structure of organoantimony (V) cyclometallates: Transannular interactions and the barrier to cyclisation (2001)
Journal Article

A variety of α-hydroxy carboxylic acid salts [AgO2CC(OH)R1R2] react with SbPh3Cl2 1 to afford the cyclometalled complexes 4b-g. A single crystal X-ray analysis of (±)-4g reveals the presence of conformational diastereoisomers arising from the helical...

Characterising secondary bonding interactions within triaryl organoantimony(v) and organobismuth(v) complexes (2000)
Journal Article

The thermodynamically preferred conformations of the five-co-ordinate trigonal-bipyramidal complexes SbPh3CI21 and BiPh3Cl2 2, determined via van der Waals energy calculations, have been found to be in good agreement with the corresponding correlated...

The conformational analysis of phosphine ligands in organometallic complexes: Part 2: Triphenylphosphine coordinated to achiral and prochiral octahedral metal centres (1999)
Journal Article

The novel concept of nadir energy planes has been used to illuminate the principles governing the preferred orientation of rings A-C in PPh3 1, coordinated to achiral octahedral metal complexes of the type [M(PPh3)L1-5] 2a-d, and prochiral octahedral...

The conformational analysis of phosphine ligands in organometallic complexes: Part 1: Triphenylphosphine coordinated to an achiral metal centre 1 (1998)
Journal Article

The conformational analyses of PPh3 1 and the representative achiral metal complexes [Al(PPh3)(Me)3] 2, [Fe(PPh3)(CO)4] 7 and [Ir(PPh3)2(CO)3]+ 8 possessing tetrahedral and trigonal-bipyramidal geometries are reported, and comparisons between the cal...
