Triphenyl Antimony, Salicylaldehyde Synthesis And Properties Of Amino Acid And Its Organotin Complexes

The present paper main task involves some organotin and organostibine compands and the intermediate of photoresist synthesis research, mainly includes the following content:1. The synthesis of triphenylstibine:Triphenylstibine is an important intermediate which derivatives can be use in many ways. For example, it's dihalidee can be used as flame retardant; oxides can catalyze the synthesis of dipeptide; the hydrogenation can be accelerated by its composition with Pd,Rh,Co,Ru.It is also a powerful anti-fungal,anti-oxidation, catalysis and help to deprivate halogen, and so on.Triphenylstibine was prepared with metal sodium, chlorobenzene and antimony trichloride in toluene.The ratio of raw materials,reaction temperature and time that affect the product properties were investigated.The optimum synthetical conditions were : the metal sodium, chlorobenzene and antimony trichloride ratio was 1:1.95～2:1/3,airless temperature under 40℃for about 2-3 hours.It also can be synthesized with magnesium, chlorobenzene and antimony trichloride by the way of Grignard reagent, too. The ratio of raw materials,reaction temperature and time that affect the product properties were investigated.The optimum synthetical conditions were : the metal magnesium, chlorobenzene and antimony trichloride ratio was1:1.1-1.3:1/3,airless temperature under 60℃for about 2-3 hours.2. The synthesis of p-ethoxystyrene:p-ethoxystyrene is an important intermediate of photoresist.The raw materials is p-bromine ethoxybenzene,magnesium and aldehyde without water.At first,Grignard reagent react with aldehyde,and then acid,extract with acetic ether,distil with less pressure,collect distillation cut in 91—94℃/5mmHg,yield exceed 30%.3. The synthesis of new schiff base and their organotin compands.The new schiff base is condensed with salicylaldehyde and (aminooxy)acetic acid.It is in great use of catalysis, preparation, stabilizing agent, sterilization, anti-canser activity of organotin compands which let a lot of chemists over the world pay attention to them.Because that amino acid can enhance fat-soluble ability and relax the toxicity to cellular in medical molecular, help to give high electronegativity atoms,such as oxygen and nitrogen,have many co-ordination patterns and better co-ordination ability, this kind of compands have the power of control cancer, kill bacteria amd caducity. But , we studied a lot of Schiff base of natural amino acid instead of man-maded.New schiff base was synthesized with salicylic aldehyde, (aminooxy)acetic acid hydrochloride in refluxing methanol. The ratio of raw materials, reaction temperature and time that affect the product properties were investigated.The optimum synthetical conditions were: the salicylic aldehyde, (aminooxy)acetic acid hydrochloride and potassium hydroxide ratio was 1.0:1.0:1.5, airless and anhydrous. Their organotin compands were charactered with IR, NMR and so on.
