Quinone methide dimers lacking labile hydrogen atoms are surprisingly excellent radical-trapping antioxidants
Raycroft M, Chauvin J, Galliher M, Romero K, Stephenson C, Pratt D
Chem Sci . 2020 Aug; 11(22):5676-5689. PMID: 32832049
Hydrogen atom transfer (HAT) is the mechanism by which the vast majority of radical-trapping antioxidants (RTAs), such as hindered phenols, inhibit autoxidation. As such, at least one weak O-H bond...

Base-Promoted C-C Bond Activation Enables Radical Allylation with Homoallylic Alcohols
Lubbesmeyer M, Mackay E, Raycroft M, Elfert J, Pratt D, Studer A
J Am Chem Soc . 2020 Jan; 142(5):2609-2616. PMID: 31941267
The C-C bond in homoallylic alcohols can be activated under basic conditions, qualifying these nonstrained acyclic systems as radical allylation reagents. This reactivity is exemplified by photoinitiated (with visible light...

Electrochemical Dimerization of Phenylpropenoids and the Surprising Antioxidant Activity of the Resultant Quinone Methide Dimers
Romero K, Galliher M, Raycroft M, Chauvin J, Bosque I, Pratt D, et al.
Angew Chem Int Ed Engl . 2018 Nov; 57(52):17125-17129. PMID: 30474921
A simple method for the dimerization of phenylpropenoid derivatives is reported. It leverages electrochemical oxidation of p-unsaturated phenols to access the dimeric materials in a biomimetic fashion. The mild nature...

Mechanisms of Alkyl and Aryl Thiol Addition to N-Methylmaleimide
Raycroft M, Racine K, Rowley C, Keillor J
J Org Chem . 2018 Sep; 83(19):11674-11685. PMID: 30180571
A mechanistic study was undertaken to elucidate the reaction pathways for thiol addition to N-methylmaleimide in water. We used linear free energy relationships, solvent kinetic isotope effects (SKIEs), activation parameters,...

Rapid Ni, Zn, and Cu ion-promoted alcoholysis of N,N-bis(2-picolyl)- and N,N-bis((1H-benzimidazol-2-yl)methyl)-p-nitrobenzamides in methanol and ethanol
Raycroft M, Cimpean L, Neverov A, Brown R
Inorg Chem . 2014 Feb; 53(4):2211-21. PMID: 24491210
The methanolysis and ethanolysis of the Ni(II), Zn(II), and Cu(II) complexes of N,N-bis(2-picolyl)-p-nitrobenzamide (1) and N,N-bis((1H-benzimidazol-2-yl)methyl)-p-nitrobenzamide (2) were studied under pH-controlled conditions at 25 °C. Details of the mechanism were...

Trifunctional metal ion-catalyzed solvolysis: Cu(II)-promoted methanolysis of N,N-bis(2-picolyl) benzamides involves unusual Lewis acid activation of substrate, delivery of coordinated nucleophile, powerful assistance of the leaving group departure
Raycroft M, Maxwell C, Oldham R, Andrea A, Neverov A, Brown R
Inorg Chem . 2012 Sep; 51(19):10325-33. PMID: 22971051
The methanolyses of Cu(II) complexes of a series of N,N-bis(2-picolyl) benzamides (4a-g) bearing substituents X on the aromatic ring were studied under (s)(s)pH-controlled conditions at 25 °C. The active form...

Comparison of Cu(II)-promoted leaving group stabilization of the cleavage of a homologous set of phosphate mono-, di-, and triesters in water, methanol, and ethanol
Raycroft M, Liu C, Brown R
Inorg Chem . 2012 Mar; 51(6):3846-54. PMID: 22397727
The cleavage of a set of phosphate mono-, di-, and triesters having a Cu(II)-complexed 2-phenanthrolyl group at the ortho-position of a departing phenoxide was studied in water and ethanol. Experimentally...
