The desulfurization of 1,1-bis(phenylthio)-2-alkynes with the titanocene(II) species Cp2Ti[P(OEt)3]2 in the presence of 1-alkenes produced 1-alkyn-1-ylcyclopropanes in good yields.
Substitution of the acetoxy groups of dialkoxymethylacetates by organometallic reagents: a route to allyl-, propargyl-, homoallyl-, homopropargyl- and α-stannylacetals

The substitution of the acetoxy groups of dialkoxymethylacetates by organometallic reagents has been examined in a search for new methods of preparing functional acetals.The efficiency of the substitution of the acetoxy group is highly dependent on the nature of the organometallic reagents: soft nucleophiles with strong electrophilic assistance by the counterion are the best reagents.Allyl-, propargyl-, homoallyl-, homopropargyl- and α-stannylacetals have been made by this route, in which dialkoxymethylacetates often function as useful substitutes for dialkylphenylorthoformates.

The reaction of dialkylphenylorthoformiates with organometallic compounds proceeds with a good yield, at room temperature, giving the corresponding dialkylacetals ; it allows an easy preparation of acetals which are otherwise difficult to prepare.
