Description
Technical Field
A method for selectively preparing an alkenyl silane.
Background
Organic silicon is used as an important chemical raw material and widely applied to the fields of buildings, electronic industry, medicines, foods and the like [ see: (a) silicon,2009,1,147, (b) chem.rev.,2010,110,1233, (c) chem.soc.rev.,2011,40,696 ]. Although the preparation of such compounds using transition metal catalysis has been well reported [ see: (a) nat. rev. chem.,2018,2,15.(b) Science,2002,298,204.(c) RSC adv.,2015,5,20603.], but there are several problems in general with the silylation reaction of olefins, that (i) reaction by-products are large; secondly, the hydrogen silication product is mainly used, and the high-efficiency synthesis of the dehydrosilicification product is rarely reported; the applicability of the substrate is poor; and fourthly, in the dehydrosilicification reaction, an extra hydrogen acceptor or an oxidant is needed, and the atom economy is poor. Meanwhile, manganese is used as a nontoxic and environment-friendly metal, is rich in earth crust, shows good water and oxygen tolerance compared with other low-valence metals such as Fe, Co, Ni and the like, and a recently reported manganese-catalyzed synthesis strategy mainly relates to a hydrogen hydrogenation reaction of olefin. Dehydrosilicidation reacts with moderate selectivity with some activated olefins and silanes with large chemical resistance, but with poor compatibility with non-activated olefins and complex molecules and other classes of silanes [ see: (a) chen.j.chem., 2018,36,1047, (b) chem.asian, 2018,13,2307. Therefore, the development of an efficient synthetic method for preparing alkenylsilanes and alkylsilanes with high selectivity has been the focus of research in this field. Under the condition of not adding any additive, the silanization reaction of various types of olefins including gases such as ethylene, propylene and the like is realized only by regulating and controlling the ligand, and the synthetic method is simple and efficient and has great industrial application potential.
Disclosure of Invention
The technical problem to be solved by the invention is to realize the selective silylation reaction of olefin by regulating and controlling the ligand and the application thereof.
The synthetic route of the invention is as follows:
a selective preparation method of alkenyl silane, it takes terminal olefin (1) and trisubstituted silane (2) as raw materials, take trifluorotoluene as solvent, react for 24-36 hours under the influence of ligand 1 at 115-:
in the above preparation method, the terminal olefin (1) may be ethylene, propylene and butylene or activated olefin or non-activated olefin with various substituents and some terminal olefins containing complex structures.
In the above preparation method, the R groups of the trisubstituted silane (2) can be the same or different.
In the preparation method, the R group of the trisubstituted silane (2) can be ethyl, ethoxy, trimethylsiloxy, alkyl or cycloalkyl.
In the preparation method, the reaction condition is under the air condition, and no inert gas needs to be additionally filled.
In the preparation method, the mol ratio of the terminal olefin to the tri-substituted silane is 1: 1.
In the above production method, in the production of the dehydrosilicidation product, the catalyst decacarbonyldimanganese is used in an amount of 5 mol% based on the terminal olefin (1), and the ligand 1 is used in an amount of 10 mol% based on the terminal olefin (1).
A typical reaction is as follows:
the method disclosed by the invention is simple and efficient, high in selectivity, strong in substrate applicability and high in raw material utilization rate, especially initially realizes single selectivity under ligand regulation in the direction of dehydrosilicification, and avoids the problems of quality reduction and difficult separation caused by introduction of byproducts in the industrial application process.
