“…Indeed, in terms of isolable oxonium species, trialkyloxonium salts with inert counterions (such as BF 4 − or PF 6 − ) are the most powerful alkylating agents one is likely to encounter in the laboratory. In general, they are prepared either by the reaction of an epoxide with an ether in the presence of a Lewis acid, from orthoformates and ethers via dialkoxy-carbenium salts, by the reaction of diazoalkanes with ethers in the presence of an acid with a non-nucleophilic counterion, or by simple alkylation of ethers with alkyl halides in the presence of Lewis acids or silver salts . Herein, we report the synthesis of oxatriquinane ( 1 ) and oxatriquinacene ( 2 ), the rigid, tricyclic frameworks of which impart to them properties unheard of in alkyl oxonium ion chemistry.…”

“…2-Methyl-1,3-dioxolan-2-yilium cations, 11, were synthetically first studied by Meerwein [15][16][17][18][19][20][21][22] and further explored in the pioneering solvolytic studies of Winstein [23][24][25][26][27][28][29]. This type of cation is widely formed as an intermediate in the reactions of mono and polysaccharides [30][31][32][33][34][35][36][37][38].…”

“…This type of cation is widely formed as an intermediate in the reactions of mono and polysaccharides [30][31][32][33][34][35][36][37][38]. Stable salts were isolated [17,39,40], and these cations were shown to be stable in strong acids where their NMR spectra were recorded [41]. The high stability of 2-substituted-1,3-dioxolan-2-ylium ions is illustrated by their quantitative formation from the corresponding 2-substituted-1,3-dioxolanes via hydride abstraction by the stable triphenylmethyl cation [21].…”
