Combining electronic and steric effects for highly stable unsymmetric pentacenes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zhang J, Pawle RH, Haas TE, Thomas SW.
PMID: 24623650
Chemistry. 2014 May 12;20(20):5880-4. doi: 10.1002/chem.201402003. Epub 2014 Mar 13.

This paper describes the reactivity of unsymmetrically substituted pentacenes to photochemical oxidation. Acenes in general, and pentacenes in particular, are a key family of compounds for a variety of organic electronics applications. The instability of many pentacene derivatives, particularly...

Direct conjugate alkylation of α,β-unsaturated carbonyls by Ti(III)-catalysed reductive umpolung of simple activated alkenes.

Organic & biomolecular chemistry

Bichovski P, Haas TM, Keller M, Streuff J.
PMID: 26806535
Org Biomol Chem. 2016 Jun 15;14(24):5673-82. doi: 10.1039/c5ob02631h.

The titanium(iii)-catalysed cross-selective reductive umpolung of Michael-acceptors represents a unique direct conjugate β-alkylation reaction. It allows the cross-selective preparation of 1,6- and 1,4-difunctionalised building blocks without the requirement of stoichiometric organometallic reagents. In this full paper, the development and...

Testosterone replacement and cardiovascular safety: no straight and narrow!.

Clinical Medicine Insights. Cardiology

Hans SS, Dhindsa SS, Chemitiganti R.

Bu(3)SnH-Mediated Pinacol Coupling of 1,5- and 1,6-Dicarbonyl Compounds: Synthetic and Mechanistic Studies.

The Journal of organic chemistry

Hays DS, Fu GC.
PMID: 11672272
J Org Chem. 1998 Sep 04;63(18):6375-6381. doi: 10.1021/jo9809130.

A new method is described for the intramolecular pinacol coupling of 1,5- and 1,6-dicarbonyl compounds, employing Bu(3)SnH as the stoichiometric reductant. The key steps in this pinacol cyclization are the addition of a tin ketyl to a carbonyl group...

Edge temperature gradient as intrinsic rotation drive in Alcator C-Mod tokamak plasmas.

Physical review letters

Rice JE, Hughes JW, Diamond PH, Kosuga Y, Podpaly YA, Reinke ML, Greenwald MJ, Gürcan ÖD, Hahm TS, Hubbard AE, Marmar ES, McDevitt CJ, Whyte DG.
PMID: 21699305

Intrinsic rotation has been observed in I-mode plasmas from the C-Mod tokamak, and is found to be similar to that in H mode, both in its edge origin and in the scaling with global pressure. Since both plasmas have...
