    (1Z,3Z)-1-Butyltelluro-1,3-butadienes 8, 9 and 12 obtained by the hydrotelluration of but-1-en-3-ynes 1, 2 and 5 were transformed into the corresponding buta-1,3-dienyl-1-lithium by reaction with n-BuLi. 1,3-Butadienes 14, 15, 17-20 were obtained with retention of the double bond geometry by reaction of the butadienyllithium intermediates with electrophiles. The butadienyllithium 13 obtained by the Te/Li exchange reaction in the (12,3Z)-1-Butyltelluro-4-methoxy-1,3-Butadiene 8 was reacted with benzaldehyde to form the corresponding alcohol 15 with total retention of configuration, that undergoes hydrolysis resulting into the (E,E)-5-phenyl-2,3-pentadien-1-al 16.

    ArF (193 nm) and KrF (248 nm) laser-induced photolysis of gaseous selenophene and tellurophene (C4H4M, M=Se and Te) has been examined. It is shown that, unlike thiophene and furan, selenophene and tellurophene cleave both M-C bonds and yield the elemental heteroatom (Se, Te), 1-buten-3-yne, and ethyne. The proposed mechanism involves an intermediate .HC=CH-CH=CH. diradical that decomposes via two competitive
