Acetone promoted 1,4-migration of an alkoxycarbonyl group on a syn-1,2-diamine.

Tetrahedron letters

Napolitano T, Cheng SY, Nielsen B, Choi C, Aguilar W, Paz MM, Sapse AM, Champeil E.
PMID: 28943668
Tetrahedron Lett. 2017 Feb 15;58(7):597-601. doi: 10.1016/j.tetlet.2016.12.047. Epub 2017 Jan 03.

A 2-protected cis-amino mitosene undergoes an irreversible acetone promoted isomerization and converts to the 1-isomer. Kinetic studies and DFT calculations of the reaction are reported. An organocatalytic mechanism is proposed, involving a covalent intermediate formed by reaction of the...

Adv Mater. 2017 Mar;29(12). doi: 10.1002/adma.201605092. Epub 2017 Feb 09.

Room-temperature quantum emitters in gallium nitride (GaN) are reported. The emitters originate from cubic inclusions in hexagonal lattice and exhibit narrowband luminescence in the red spectral range. The sources are found in different GaN substrates, and therefore are promising...

Synthesis of guanidinium-sulfonimide ion pairs: towards novel ionic liquid crystals.

Beilstein journal of organic chemistry

Butschies M, Neidhardt MM, Mansueto M, Laschat S, Tussetschläger S.

Beilstein J Org Chem. 2013 Jun 05;9:1093-101. doi: 10.3762/bjoc.9.121. Print 2013.

The recently introduced concept of ionic liquid crystals (ILCs) with complementary ion pairs, consisting of both, mesogenic cation and anion, was extended from guanidinium sulfonates to guanidinium sulfonimides. In this preliminary study, the synthesis and mesomorphic properties of selected...

Kohn-Sham Density Functional Theory Electronic Structure Calculations with Linearly Scaling Computational Time and Memory Usage.

Journal of chemical theory and computation

J Chem Theory Comput. 2011 Feb 08;7(2):340-50. doi: 10.1021/ct100611z. Epub 2010 Dec 30.

We present a complete linear scaling method for hybrid Kohn-Sham density functional theory electronic structure calculations and demonstrate its performance. Particular attention is given to the linear scaling computation of the Kohn-Sham exchange-correlation matrix directly in sparse form within...

Aeromonas spp. are Gram-negative rods ubiquitous in aquatic environments; however, some species are able to cause a variety of infections in humans. Here, we report the draft genome sequence of Aeromonas caviae 8LM isolated from stool culture from a...

The boron-catalyzed polymerization of dimethylsulfoxonium methylide. A living polymethylene synthesis.

Journal of the American Chemical Society

Busch BB, Paz MM, Shea KJ, Staiger CL, Stoddard JM, Walker JR, Zhou XZ, Zhu H.
PMID: 11929253
J Am Chem Soc. 2002 Apr 10;124(14):3636-46. doi: 10.1021/ja017376c.

Trialkyl and aryl organoboranes catalyze the polymerization of dimethylsulfoxonium methylide (1). The product of the polymerization is a tris-polymethylene organoborane. Oxidation affords linear telechelic alpha-hydroxy polymethylene. The polymer molecular weight was found to be directly proportional to the stoichiometric...
