Abstract
The invention discloses a chiral oxazolinyl cobalt complex and synthesis method thereof. The chemical formula is shown in the specification. The synthesis method comprises the following steps: in the presence of 50.0mol% cobalt chloride hexahydrate serving as a catalyst and 50mL of chlorobenzene as a solvent, performing a reflux reaction on 20.0mmol of hydroxybenzonitrile and 4.4391g of D-phenylglycinol for 72 hours, purifying, removing chlorobenzene at then end of the reaction, dissolving with water, leaching by using chloroform, purifying by using column chromatography after a leaching phase is subjected to desolvation; preparing a saturated liquid by using trichloromethane/ethanol, and naturally volatilizing to obtain a chiral oxazolinyl cobalt complex monocrystal. The complex shows a certain catalyzing performance in Henry reactions of benzene and methanal and the yields respectively reach 88.4 percent.
Description
one, technical field
The present invention relates to a kind of organometallic complex (title complex) and preparation method thereof, particularly nitrogenous oxazoline a metal-organic complex and preparation method thereof, is exactly a kind of cobalt complex and synthetic method thereof of chirality phosphine acyl Shuan An oxazoline.
two, background technology
Along with vitochemical development, the application of organometallics in organic synthesis is more and more wide, is one of field very active in present organic chemistry, is widely used in organic synthesis.The use chiral ligand that the later stage sixties 20th century occurs and the asymmetric catalysis synthesis of transition metal complex catalysis have accelerated the research of chiral drug greatly.The important content of chemical catalysis dissymmetric synthesis is the design of chiral ligand and containing metal catalyzer, thereby makes reaction have efficient and high enantioselectivity.Shou bisoxazoline part one cobalt metal compounding synthetic has many bibliographical informations in recent years.
