METHOD FOR PRODUCING 14 GROUP METAL LITHIUM COMPOUND

PROBLEM TO BE SOLVED: To provide a method for quantitatively producing a group 14 metal lithium compound under a mild condition. SOLUTION: The method for producing a group 14 metal lithium compound represented by formula (4): R4-nMLin comprises reacting a compound represented by formula (1): R4-nMXn and lithium in the presence of a polycyclic aromatic compound represented by formula (2) or formula (3). [In formula (1) and formula (2), R is a hydrocarbon group; M is a metal atom selected from Si, Ge and Sn; X is a halogen atom or R3M- (R and M are the same as mentioned above); and n is 1 or 2] and [R1 is H or a hydrocarbon group; and m is an integer of 0 to 5.] SELECTED DRAWING: None COPYRIGHT: (C)2016,JPOandINPIT

A Sn atom-economical approach toward arylstannanes: Ni-catalysed stannylation of aryl halides using Bu3SnOMe

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.

Stannyl-Lithium: A Facile and Efficient Synthesis Facilitating Further Applications

We have developed a highly efficient, practical, polycyclic aromatic hydrocarbon (PAH)-catalyzed synthesis of stannyl lithium (Sn-Li), in which the tin resource (stannyl chloride or distannyl) is rapidly and quantitatively transformed into Sn-Li reagent at room temperature without formation of any (toxic) byproducts. The resulting Sn-Li reagent can be stored at ambient temperature for months and shows high reactivity toward various substrates, with quantitative atom efficiency.

New and simple one-step cobalt-catalyzed preparation of functionalized arylstannanes from the corresponding aryl bromides or iodides

The process for the preparation of functionalized arylstannanes from the corresponding aryl bromides or iodides was described. The corresponding arylstannane was detected by gas chromatography using an internal standard alkane. The two-step coupling react
