Abstract
Gas-phase reactions of CnH5+ (n = 1, 2) with oxetane (I) and 2-methyloxirane (II) and of MeCFH3+ (III) with oxirane initially gave the O-protonated or O-methylated cations of the cyclic ether; these reacted with nucleophiles present. I and II gave mixts. of I, CH2:CHOMe, HOCH2CH2OMe (IV) and/or EtCHO, whereas III gave only IV. This is the 1st exptl. evidence for 1-methyl-1-oxoniacyclopentane and -cyclobutane as stable intermediates on the corresponding potential-energy surface.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
