(Z)-1-phenyl-1-(p-fluorophenyl)-2-(p-tosyl)-1,4-pentadiene(1) was synthesized by the three-component tandem reaction of 1-phenyl-2-(p-tosyl)ethyne,p-fluorophenylzinc chloride and allyl bromide.

Using the Theory of Collision and Activated-energy and Transition state illustrates the reason of seldom-seen of trimolecular reaction.

The new proof about the existence,uniqueness and stablity of limit cycle of a nonlineardifferential equation derived from experiment of trimolecular reaction and its global constrction areobtained,by analysising the properities of its singluarity at infinity.

The pheomenon of self-pulsating of a trimolecular reaction system is discussed,and the result that when reaction material consistency A is smaller than its critical value, the periodic solution of this system is always stable is obtained.

The title compound has been synthesized via microwave-assisted multicomponent reaction of thiophene-2-carbaldehyde with 5,5-dimethyl-3-(methylamino)cyclohex-2-enone and 1,3-indanedione in HOAc,and its structure was determined by monocrystalline X-ray diffraction.

This paper mainly studied on multicomponent reaction which was catalyzed by solid acid, including (1) one-pot preparation ofβ-acetamido ketones via a three-component condensation reaction ; (2) synthesis ofβ-enaminones; (3) p.

An example is the chemist focus on the multicomponent reactions based on ketenimine intermediates.
