We have developed photoboosted stannylation reactions of terminal alkynes (linear-selective hydrostannylation) and fluoroarenes (defluorostannylation), in which the stannyl anion is photoexcited to an excited triplet (T1) stannyl diradical species. This u

Paragraph 0045-0049, (2018/12/14)
The invention discloses a method for converting substituted sodium acryl sulfonate to aryl tri-n-butyltin. The synthetic method of the aryl tri-n-butyltin compound comprises the following steps: uniformly mixing sodium aryl sulfonate, silver carbonate, bis(tri-tert-butylphosphine)palladium, and hexabutyldistannane in a solvent, reacting for 1 to 8 hours at 80 to 140 DEG C, and after the reaction is ended, concentrating; and performing the column chromatography, and obtaining a pure aryl tri-n-butyltin product. The adopted raw material is sodium aryl sulfonate which is significant in supplementation, wide in source, cheap and easy to obtain compared with the existing method adopting aromatic halides as a raw material. The reaction in the invention has good tolerance and universality for a functional group, and the substituent group can be hydrogen, methyl, tertiary butyl, fluorine, chlorine, bromine, cyanogroup, trifluoromethyl, nitro, acetyl or carbethoxy.

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.
