They are among the strongest punnett square chemical bonds: nitrogen-nitrogen (in molecular nitrogen, N 2) and carbon-oxygen (in carbon monoxide, CO). American chemists now published punnett square in Nature Chemistry a way to break these bonds and the fragments into new molecules. They predict a whole new synthesis route in which chemicals and materials are made out of atmospheric gases, instead of from petroleum.
The triple bonds between atoms in the nitrogen molecule to let himself recently not break in an easier way. Chemists led by Paul Chirik of Cornell University in New York (US) found a way to do so. Even at room temperature, and atmospheric pressure.
Chirik and colleagues made include oxamide, a known fertilizer. However, by changing the amount of carbon monoxide can also be made of other hydrocarbons. And from there, the way is open for products that still originate from petroleum.
In the new process is all about hafnocene, a molecular complex of hafnium and cyclopentadiene molecules. Two of these complexes include a nitrogen molecule in the hold, and thereby reduce the strength of the NN bond. This makes it possible to form a compound with carbon monoxide. punnett square In a next reaction punnett square step, the entire structure from falling out of each other under the formation of new molecules. C & EN
Nevertheless, the industrial relevance of the new process for the time being not yet very large. The hafnium compound is consumed namely: for each broken N 2 molecule is a new hafnium complex needed. More preferably, the chemists see a catalytic route wherein the activating complexes are retained. Chirik see that as a challenge. He reported to the British tijschrift Chemistry World: "We have now uncovered a new reaction environment, and a new transformation that we hope to use in catalytic reactions and important industrial processes."
"Whenever somebody new chemical conversion takes place for the nitrogen punnett square molecule we get closer to a solution to one of the holy grails of chemistry," says the Canadian scientist Michael Fryzuk of the University of British Columbia (Vancouver, punnett square Canada) in a reaction to 'Chemistry World.
