Beyond the Simple Copper(II) Coordination Chemistry with Quinaldinate and Secondary Amines

Molecules, 2020
Copper(II) acetate has reacted in methanol with quinaldinic acid (quinoline-2-carboxylic acid) to form [Cu(quin)2(CH3OH)]∙CH3OH (1) (quin− = an anionic form of the acid) with quinaldinates bound in a bidentate chelating manner.

Phosphine-Catalyzed Annulations of Azomethine Imines: Allene-Dependent [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3] Pathways [PDF]

, 2011
In this paper we describe the phosphine-catalyzed [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3] annulations of azomethine imines and allenoates. These processes mark the first use of azomethine imines in nucleophilic phosphine catalysis, producing ...

Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches

Chemistry – A European Journal, EarlyView.
We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

5,11-Dimethyldibenzo[b,f][1,5]diazocine-6,12(5H,11H)-dione

Acta Crystallographica Section E, 2008
In the molecule of the title compound, C16H14N2O2, an N,N′-dimethyldianthranilide, the two methyl groups are disordered over two positions; site occupation factors were kept fixed as 0.75:0.25 and 0.65:0.35.

Reproductive Mechanisms Influenced by a Diazocine

Experimental Biology and Medicine, 1965
Summary2,8-Dichloro-6,12-diphenyl-dibenzo[b,f][l,5] diazocine completely inhibited pregnancy when administered either orally or subcutaneously to female rats at doses as low as 0.5 mg daily for 7 days at time of mating. At higher doses, single treatments prior to completion of implantation were equally effective.

A Density Functional Theory Study of the Structural Preferences of Type B Heteropentalene Mesomeric Betaines and Their Non‐Aromatic Azacyclooctatetraene Isomers

Journal of Heterocyclic Chemistry, Volume 63, Issue 5, Page 778-784, May 2026.
DFT has been used to rationalize the relative stabilities of the Type B heteropentalene mesomeric betaines (HMBs) and their azacyclooctatetraene isomers; the tetraaza and triaza HMBs are generally expected to be thermodynamically more stable than their azacyclooctatetraene isomers, whereas the converse is true for diaza systems.

Novel photochromic liquid crystals [PDF]

, 2016
The combination of photochromic units and liquid crystal mesogens has over the years been investigated intensively. However the focus of this work has been on very few photochromic groups.
