Gold( i ) catalyzed cascade cyclization: intramolecular two-fold nucleophilic addition to vinylidenecyclopropanes (VDCPs).
Novel 1,2,3-triazole compounds 3–4 were synthesised via the regioselective addition and cyclization reaction of 1,1-enediamines (EDAMs) 1 with p-methylbenzenesulfonyl azide (TsN3) 2 in 1,4-dioxane at refluxing for 5 hours. For SN2 reactions, alkyl alcohols can also be converted to alkyl tosylates, often through addition of tosyl chloride. To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

The diazo group is an organic moiety consisting of two linked nitrogen atoms at the terminal position.Overall charge neutral organic compounds containing the diazo group bound to a carbon atom are called diazo compounds or diazoalkanes and are described by the general structural formula R 2 C=N + =N –.The simplest example of a diazo compound is diazomethane, CH 2 N 2.

The tosylate group may later be converted back into an alcohol. Electronic Supporting Information files are available without a subscription to ACS Web Editions. It is the transformation of alkyl alcohols to alkyl tosylates that allows an SN2 reaction to occur in the presence of a good nucleophile.
