An unprecedented conversion of methyl esters to stannanes was realized, providing access to a series of arylstannanes via nickel catalysis. Various common esters including ethyl, cyclohexyl, benzyl, and phenyl esters can undergo the newly developed decarbonylative stannylation reaction. The reaction shows broad substrate scope, can differentiate between different types of esters, and if applied in consecutive fashion, allows the transformation of methyl esters into aryl fluorides or biaryls via fluororination or arylation.

The invention provides a tetraphenylmethane or silane-based compound shown in formula (I), a preparation method of the tetraphenylmethane or silane-based compound and application of the tetraphenylmethane or silane-based compound in synthesizing an electrochromic material membrane as a monomer. As the tetraphenylmethane or silane-based compound has a space structure of tetrahedral tetrad, through membrane formation with electrochemcial polymerization, the obtained membrane expresses larger specific surface area and good electrochemical performance such as electrochromism and the like at the same time. The contrast of the membrane is 30-80 percent, the response time of the membrane is between 0.5s and 6s, the contrast and the response time both express reasonable electrochemcial stable activity, and experimental results show that the material is a potential electrochromic material. The formula of the tetraphenylmethane or silane-based compound is shown in the description.

Stannylation of carbon-halogen bonds is one of the most promising and straightforward approaches for the preparation of organostannane compounds. Although a wide variety of methods are now available, all protocols require the use of highly nucleophilic organometals or wasteful stannyl sources like distannanes. Here, we report a new nickel-catalysed stannylation of aryl and alkenyl-halides using Bu3SnOMe as a stannyl source to afford aryl and vinyl-stannanes, respectively. This method enables the stannylation of not only bromides, but also chlorides and triflates to furnish functionalized aryl- and alkenyl-stannanes without the release of wasteful and toxic stannyl byproducts.
