Compound 1O undergoes a thermally initiated cyclization reaction to give the benzoxaphosphastannole derivative {1(P),3(Sn)-Sn(S-Py)2-OP(O)(O-i-Pr)-6-t-Bu-4-P(O)(Oi-Pr)2}C6H2 (11). The compounds were characterized by H-1, C-13, P-31,Sn-119, and Te-125 NMR and IR spectroscopy, electrospray ionization mass spectrometry, and single-crystal X-ray diffraction analysis. The intramolecular Sn-N and Sn-O distances range between 2.501(3) (2) and 2.815(3) angstrom (4) and between 2.407(2) (8 center dot C7H8) and 2.497(2) angstrom, respectively. Compounds 6 and 7 show intermolecular secondary Sn center dot center dot center dot Sn interactions at distances of 3.8876(3) and 3.8379(5) A, respectively.
