eng	Reactivity of a C,N-Chelated Stannoxane	The stannylene {2-[(CH3)(2)NCH2](2)C6H4}(2)Sn (1) did not react with CO2 at room temperature and atmospheric pressure, but its oxidation product {[2-[(CH3)(2)NCH2](2)C6H4](2)Sn-(mu-O)}(2) (2) is very reactive toward CO2 to give the cyclic compound {[2-[(CH3)(2)NCH2](2)C6H4}(2)Sn](2)(mu-O)(mu-CO3) (2b). The product of reaction of 2 with silicon grease is also a cyclic compound with an eight-membered ring, {{{2-[(CH3)(2)NCH2](2)C6H4}(2)Sn}(Me2SiO)}(2) (2c), as the structural characterization revealed (XRD). Triphenylsilanol condensates with 2 to form {2-[(CH3)(2)NCH2](2)C6H4}(2)Sn(OSiPh3)(2) (2b). The reaction of 2 with ethylene glycol gave the cyclic compound {2-[(CH3)(2)-NCH2](2)C6H4}(2)Sn(OCH2CH2O) center dot 1/2(HOCH2CH2OH)(2e).	C,N-Chelated Stannoxane
