Grignardreagents react, in ether and at room temperature, with propargylic ethers, to give allenic hydrocarbons with reasonable yields. The reactions requires catalytic amounts of copper(I) bromide.

[reaction: see text] Triorganoindiumreagents (R(3)In) react with propargylic esters under palladium catalysis via an S(N)2' rearrangement to afford allenes in good yields and with high regioselectivity. The reaction proceeds smoothly at room temperature with a variety of R(3)In (aryl, alkenyl, alkynyl, and methyl). When chiral, nonracemic propargylic esters are employed, the reaction takes place with
