Abstract

Abstract The cycloadditions of carbon dioxide, isocyanates and carbodiimides to oxetanes proceeded in the presence of catalytic amounts of tetraphenylstibonium iodide (1) under mild conditions, affording the corresponding six-membered heterocycles; 1, 3-dioxan-2- ones, 1, 3-oxazin-2-ones and 1, 3-oxazin-2-imines in good yields, respectively. Moreover, the cycloaddition of 2-phenyloxetane proceeded via predominant ring-cleavage at ...
