Presence of Iodosobenzene Diacetate: Direct Synthesis of 3-Functionalized-2-aryl-selenyl Substituted Allyl Derivatives. — Multicomponent reaction of aryl substituted allenes, diphenyl diselenide and oxygen nucleophiles offers a facile synthesis of vari-ous title compounds. When alkyl-substituted allenes (V) are used, the attack of the oxygen nucleophile occurs at the C-3 carbon. — (YU, L.; CHEN, B.; HUANG*, X.; Tetrahedron Lett. 48 (2007) 6, 925-927; Dep.
