Shining light on the Hantzsch reaction

10 Apr 2012

Scientists from the Indian Institute of Technology have investigated the effect of visible light on the Hantzsch reaction – a method by which to produce dihydropyridines which have found merit for cardiovascular disease treatment. By doing so, they were able to develop a photocatalytic-based methodology for producing 2-arylpyridines. Whilst such compounds are popular in medicinal chemistry and supramolecular coordination chemistry fields, their synthesis can be troublesome.

Armed with a catalytic amount of [Ru(bpy)₃]²⁺ and a household compact fluorescent lamp, the team synthesised the 2-arylpyridine compound through photocatalytic oxidation of the 1,2-dihydropyridine Hantzsch product.

Specialist Periodical Reports: Catalysis

23 Mar 2012

There is an increasing need to find cost-effective and environmentally sound methods of converting natural resources into fuels, chemicals and energy; catalysts are pivotal to such processes. Catalysis highlights major developments in this area. Coverage of this Specialist Periodical Report includes all major areas of heterogeneous catalysis. In each volume, specific areas of current interest are reviewed. Examples of topics include experimental methods, acid/base catalysis, materials synthesis, environmental catalysis, and syngas conversion.

The quest for cleaner, cheaper, more sustainable energy

12 Mar 2012

While the earth’s reserves of non-renewable energy are reducing…. our demands for energy are not. Given this is unsustainable, there is a global need to both reduce our energy consumption and develop more sustainable energy sources. Catalysis is a key player in this, potentially providing direct, efficient and economical routes to energy generation.

Here we have selected a few papers from Catalysis Science & Technology which look to develop and review catalyst based technologies for renewable energy. To mark Catalysis Science & Technology‘s recent launch, all articles are free to access for the duration of 2012.

Extended application for carbon nitride polymer

07 Mar 2012

A collaboration of scientists from Germany and China have developed a solid polymeric base catalyst for Knoevenagel condensations and transesterification reactions. The mesoporous catalyst is made from graphitic carbon nitride which has already been shown by the authors as a very promising material due to its remarkable electronic properties and large 2D-surface area (see their recent Chemical Science article here).

In their most recent Catalysis Science & Technology article, they illustrate how the incorporated nitrogen atoms display Lewis-base character that can be exploited for organocatalytic C-C coupling reactions, affording high product yield after numerous cycles.

With its ability to catalyse photoredox reactions already proven, and now its base catalytic properties, this really is a multifunctional catalyst which should find application in cascade reactions.
