Abstract

1-Methylsilatrane (I). A mixture of 1.88 g of boratrane, 2.13 g of methyltriethoxysilane, and 0.03 g of AlCl3 in 25 ml of anhydrous xylene was refluxed with simultaneous distilling off triethyl borate over 12 h. The colorless precipitate was filtered off and sublimated in a vacuum. Yield 1.94 g (86%), mp 150–153 С. IR spectrum, ν, cm–1: 596, 619, 770, 909, 946, 1019, 1096, 1125 (SiOC), 716, 816, 1253 (SiC). 1Н NMR spectrum (СDCl3), δ, ppm: 3.75 ...
