metathesis

 [mĕ-tath´ĕ-sis]
1. artificial transfer of a morbid process.
2. a chemical reaction in which an element or radical in one compound exchanges places with another element or radical in another compound.

me·tath·e·sis

(me-tath'ĕ-sis),
1. Transfer of a pathologic product (for example, a calculus) from one place to another where it causes less inconvenience or injury, when it is not possible or expedient to remove it from the body.
2. In chemistry, a double decomposition, wherein a compound, A-B, reacts with another compound, C-D, to yield A-C + B-D, or A-D + B-C.

A major reason for the success of the metathesis reaction is the well-defined catalysts that have been developed for this reaction, such as ruthenium alkylidenes 1a and 1b.
"We expect this highly flexible palette of catalysts to be useful for a wide variety of catalytic reactions that are catalyzed by a high oxidation state alkylidene species, and to be able to design catalytic metathesis reactions with a control that has rarely if ever been observed before," Schrock said.
Eight chapters are: introduction; basic chemical notions; polymerization of pristine oils and their fatty acids; monomers and polymers from chemically modified plant oils and their fatty acids; metathesis reactions applied to plant oils and polymers derived from the ensuing products; Thiol-ene and Thiol-yne reactions for the transformation of oleochemicals into monomers and polymers; Diels-Alder reactions and polycondensations applied to vegetable oils and their derivatives.

Summary: The title compound N-(2-((2,6-diisopropylphenylimino)methyl)phenyl) benzene-1,2-diamine(C25H29N3, Mr = 371.51 )was synthesized by the metathesis reactions in high yield.
