A method for the regioselective reduction of the terminal double bond of 1,1-disubstituted allenes has been developed. In the presence of a palladium catalyst, tetrahydroxydiboron and stoichiometric water, allene semireduction proceeds in high yield to afford Z-alkenes selectively.
ELECTRICAL CONDUCTIVITY OF SOME ETHYLENES AND BUTADIENES.

The effect of electron repelling groups on the conductivity of some pure aromatic semiconductors has been investigated by an electrometer method. Ethylenes and butadienes (which are ethylenes with their mirror images) in the form of compressed tablets have been chosen for this purpose. In case of ethylenes, it has been found that the resistivity increases markedly as the electron repelling effect increases, but the activation energy (1. 4 eV) remains constant. Butadienes show a similar behavior, though the relative increase in resistivity is much smaller than that of ethylenes, and the activation energy is about half as much (0. 71 eV).
