The dissertation mainly consists of two parts:1. The Reaction Chemistry of Alkynes under Palladium Catalysis Part 1 studies the reaction α,β-unsaturated carbonyl compounds with alkenylpalladium intermediate generated by nucleopalladation, and discovered 1 the Pd-catalyzed tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls,2 the four-component tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls, 3 the tandem intramolecular oxypalladation-conjugate additionreaction of alkynoic acids with α,β-enals. These new reactions provide notonly efficient highly stereoselective methods for the synthesis of γ,δ-unsaturated,polyunsaturated carbonyl compounds and γ-lactonic aldehydes, but also thebasic transformations for a number of C-C bond formation reactions which can be usedto design synthesis of many acyclic, cyclic or polycyclic compounds.

Thinking of presenting problems, this research mainly studied some solid base catalysts which own higher catalysis ability and longer lifetime. Then, the phase diagram and equilibrium data of oil-alcohol-biodiesel-glycerol multiphase system were measured because the biodiesel producing process lacks of thermodynamic data.Based on a double-membranes theory and the thermodynamic data, a kinetic model was proposed. In addition, a mult-step extraction process was proposed to dispose the jatropha curcas l oil with high acid value in order to decrease the acid value. Then, a new technology of biodiesel producing using solid base as a catalyst was developed. The study objects and results are as follows.
