The uncatalyzed ring opening of hetaryloxides with nitrogen nucleophiles. A dichotomy of regioselectivity.
摘要:
The uncatalyzed ring opening of the hetaryloxides 1, 2 and 3 with benzylamine and trimethylsilylazide has been studied being the observed regioselectivity different depending on the nucleophile used.

Epoxide formation by sulphur y1id insertion into aldehydes under heterogeneous conditions in the presence of small quantities of water is described. Trimethylsulphonium and S-methylthiolanium bromide and iodide have been studied. For all alkyl substituents the bromide gives better results than the iodide, this is interpreted in terms of the reaction mechanism. Under optimum conditions high yields of
