A new platinum-catalysed dihydroalkoxylation of alienes is described to give aliphatic acetals by an unexpected attack of two molecules of methanol to the terminal carbon of the aliene moiety. Deuteration experiments suggest an unprecedented formal 1,3-dipolar addition of methanol to a zwitterionic platinum carbene as the key step. The first platinum-catalysed intermolecular carbonbased nucleophile addition to alienes is also reported.

Free radical additions of hydrogen donor solvents (cyclohexane, dichloromethan, tetahydrofuran, dimethyl malonate and pentan-2-one) to acrolein diethylacetal allowed their 3,3 diethoxypropylation.

Reaction of lithio 2-(2,6-dimethylpiperidino)acetonitrile with alkyl halides affords monoalkylation products which are easily hydrolyzed under mild conditions to give the homogeneous aldehyde or its acetal in moderate yield.In the case of alkyl halides having an electron donating group on aromatic ring the cyclization products are obtained.
