7a, at 0 °C in diethyl ether solution. Compound 8 is stable to ambient light but decomposes in the presence of moisture or chlorinated solvents. The title compound 8 was characterized by NMR (1H, 13C, 117Sn, 119Sn) spectroscopy, HRMS, and elemental analysis. A statistical model to account for the 117Sn/119Sn coupling patterns, observed in both the 117Sn and 119Sn NMR spectra, was undertaken and is
