资源简介：
The diarylstannylene,
:Sn(AriPr4)2 (AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2), undergoes C–H metathesis
with toluene, m-xylene, or mesitylene in solutions
of these solvents at 80 °C. The products, [AriPr4Sn(CH2Ar)]2 (Aryl=C6H5 (1a), C6H4-3-Me (1b), C6H3-3,5-Me2(1c)) were characterized via 1H, 13C and 119Sn NMR, UV–vis and IR spectroscopy, and by X-ray
crystallography for 1a and 1b. A stoichiometric
amount of the arene, AriPr4H, was also
produced in these reactions. The use of EPR spectroscopy indicated
the presence of a new type of one-coordinate, tin-centered radical,
:ṠnAriPr4, resulting from Sn–C
bond cleavage in Sn(AriPr4)2.
