Polymers can be prepared using chemical and/or electrochemical methods of polymerization (see Chap. 2), although most redox polymers have been synthesized by chemical polymerization. Electrochemically active groups are either incorporated into the polymer structure inside the chain or included as a pendant group (prefunctionalized polymers), added to the polymer phase during polymerization, or ...

A general route for the synthesis of a novel class of pyridazin-3-one derivatives 3 by the reaction in acetic anhydride between 3-oxo-2-arylhydrazonopropanals 1 and some active methylene compounds like p-nitrophenylacetic acid and cyanoacetic acid was established. Under these conditions the pyridazin-3-one derivatives 3 were formed as the sole isolable products in excellent yield. The 6-acetyl-...

Fuels that can be ignited chemically under ambient conditions—upon contact with an oxidizing agent—are referred to as hypergols. Engines powered by hypergols do not require electric ignition, thus making them simple, robust, and reliable alternatives to conventional fossil fuels. Commonly used hypergolic fuels include hydrazine and its methylated derivatives, which are extremely toxic, corrosiv...

A regioselective Suzuki–Miyaura cross-coupling reaction on 3 0,5 0-dibromo pyridinium N-(2 0-azinyl)aminides is reported. A series of 3 0-aryl(or heteroaryl)-5 0-bromo-pyridinium N-(2 0-pirazinyl)aminides were obtained in good yields. Two isomeric 3 0,5 0diaryl pyridinium N-(2 0-azinyl)aminides were also prepared. 2006 Elsevier Ltd. All rights reserved. Functionalization of heterocycles through...

The purpose of a document is t o facilitate the transf e r of information f rom i ts author t o i ts readers. It is the author’s job to design the document so that the information it contains can be interpreted accurately and eficiently. To do this, the author can make use of a set of stylistic tools. In this paper we introduce the concept of document functionality, which attempts to describe t...
