Meanwhile the chemistry prize, also split three ways, was awarded for "the development of the metathesis method in organic synthesis".
Chauvin's work centred on metathesis, in which catalysts create and break double carbon bonds of organic molecules in a way that causes different groups of atoms in the molecules to change places with one another.
Such metathesis, as it is called, appears in Psalms, in which qirbam ("their inward thoughts") stands for qibram ("their grave").
The action of these catalysts yields linear polymers that retain the carbon-carbon double bonds that were present in the monomer: Such reactions are called ring-opening metathesis polymerization (ROMP) because a redistribution of the chemical bonds of the monomer occurs in forming the polymer.
Other East Anglian words show consonantal metathesis (switch position), as in singify for signify, and substitution of one liquid or nasal for another, as in chimbly for chimney and synnable for syllable.
Building on the work of Chauvin, who in the 1970s had shown how metathesis could take place, Grubbs and his associates in 1992 reported the discovery of a catalyst that contained the metal ruthenium.
A metathesis reaction is one in which compounds exchange anion-cation partners.
In addition to metathesis reactions, sulfate salts can generally be prepared by dissolution of metals in aqueous H2SO4, neutralization of aqueous H2SO4 with metal oxides or hydroxides, oxidation of metal sulfides (a sulfide contains S2−) or sulfites (SO32−), or decomposition of salts of volatile acids, such as carbonates, with aqueous H2SO4.
The form Vlach reflects South Slavic metathesis, while the name of the former Romanian kingdom of Walachia reflects East Slavic treatment.
Researchers in the 1950s had found that various catalysts could be used to carry out metathesis reaction.
An interesting reaction of the Schrock carbenes is the alkene metathesis reaction: This reaction appears to proceed through a four-membered ring intermediate containing carbon atoms and the metal atom.
