39. 1H NMR spectrum of 5 shows only a very small resonance for Sn-H end groups.
40. Detailed information is provided in the Supporting Information.
41. This method has previously been utilized for the analysis of polystannanes and is known to selectively cleave Sn-Sn bonds rather than Sn-C bonds, see: Neuman, W. P. The Organic Chemistry of Tin; Wiley: New York, 1970.
42. 1H} NMR spectrum, is 8:2.5:1.
43. To date, it has not been possible to identify or isolate any discrete products that might arise from the stoichiometric reaction between 1 and 2.
