AlkenesQ 0083 Electrophilic Addition to 1-Cyclopropylallenes: A Highly Efficient and Stereo-

selective Method for the Preparation of 6-Substituted-1,3-hexadienes. — The ad-dition of iodine to cyclopropylallenes proceeds stereoselectively giving the (Z)-isomer as sole or main product. The reaction can be extended to the formation of alcohol (III) or ethers. In the presence of alkali halides, mixtures of E/Z-isomers are obtained. — (YU, L.; MENG, B.; HUANG*, X.; Synlett 2008, 9, 1331-1334; Dep. Chem., Zhejiang Univ., Hangzhou 310028, Peop. Rep.
