A Quote by Robert H. Grubbs
Most commercial products that contain organic molecules possess at least one carbon-carbon double bond, or if one is not present, it is likely that an olefin was used in its preparation. This being the case, the potential applications of olefin metathesis are endless.

Like the Tebbe complex, ruthenium olefin metathesis catalysts can be used for the production of living polymers.
Carbon-carbon bond formation reactions employing organoboron compounds and organic electrophiles have recently been recognized as powerful tools for the construction of new organic compounds.
Carbon-carbon bond formation reactions are important processes in chemistry because they provide key steps in building complex, bio-active molecules developed as medicines and agrochemicals.
Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life-the carbohydrates, amino acids, proteins, and lipids-is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.
The buckyball, with sixty carbon atoms, is the most symmetrical form the carbon atom can take. Carbon in its nature has a genius for assembling into buckyballs. The perfect nanotube, that is, the nanotube that the carbon atom naturally wants to make and makes most often, is exactly large enough that one buckyball can roll right down the center.
Carbon is the stuff of life, and it's the stuff of everything used by human society. All of our materials are made of carbon or of substances, such as steel or glass, which are produced through the utilization of carbon.
Cutting carbon in the supply chain is the next critical stage in the business contribution to reduce carbon emissions to tackle climate change and, represents a significant commercial opportunity.
People have got to get used to making low carbon choices. If they have a direct incentive to do so they will think about it. Many times a day you have a choice between a low carbon option and a high carbon option, whether it is at home or at work.
If you don't like carbon, if you want to be zero carbon, then you might as well shoot yourself, dry up and blow away because you are carbon.
DEMAND, PURCHASE & USE LOW CARBON PRODUCTS AND SERVICES. MAKE LOW CARBON SEXY!
The palladium-catalyzed cross-coupling reaction between different types of organoboron compounds and various organic electrophiles including halides or triflates in the presence of a base provides a powerful and general methodology for the formation of carbon-carbon bonds.
Finally I got to carbon, and as you all know, in the case of carbon the reaction works out beautifully. One goes through six reactions, and at the end one comes back to carbon. In the process one has made four hydrogen atoms into one of helium. The theory, of course, was not made on the railway train from Washington to Ithaca ... It didn't take very long, it took about six weeks, but not even the Trans-Siberian railroad [has] taken that long for its journey.
Here's the problem - carbon dioxide doesn't contribute to smog and isn't a health threat. All of this is being done because some people believe carbon dioxide is causing global warming, and that preventing carbon dioxide from entering the air is the only answer. Never mind that there is still an ongoing scientific debate about global warming itself, and that some respected climate scientists believe that methane is a better target, California legislators have locked their sites on carbon dioxide.
The toxic effect of carbon monoxide on man has nothing to do with inhibition of cellular respiration by carbon monoxide but is based on the reaction of carbon monoxide with blood iron.
Our climate leadership team has recommended it go up and I would say there's always going to be upward pressure to raise the carbon tax. Remember, we're already double what the only other province who has a carbon tax is at right now, Quebec - they peg it at about $15 a tonne.
Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname 'the other carbon problem.' As they do so, the oceans become more acidic with terrible consequences.
