Bridging the gap: Bronsted acids catalyze an intramolecular S N2-type alkylation of alcohols with ethers by bridging a pentacoordinate transition state, thus simultaneously activating both the leaving group and nucleophile (see scheme). Density functional calculations provide detailed insight into the course of the reaction and the transition-state structure.

Hydroformylation of alkenes can be carried out in short time and with low syngas pressure under microwave (MW) dielectric heating. Alkenes, carrying O-, N-, or C-nucleophilic fragments, can be designed for domino reactions, mainly cyclocondensations. Ally

3,3-Diethoxypropyl-lithium is prepared by lithiation of the corresponding chlorinated precursor with lithium naphthalenide at -78 deg C; the reaction of this masked propanal homoenolate with different elctrophilic reagents CO, (CH2)7CO, PhCOMe, PhCH=NPh, PhCONEt2, PhCN, c-C6H11CN, 4-MeC6H4CN> leads to the corresponding mono- and bi-functionalized compounds.In the case of the reaction with aldehydes or ketones the prepared crude products are oxidized with m-chloroperbenzoic acid, yielding directly the γ-substituted butyrolactones.
