which gave its head-to-tail dimer 12 upon concentration of the reaction solution although it was stable in a dilute solution. Thermolysis of 12 gave an equilibrium mixture of 12, 3a, and its rotational isomer TbtaCHSe 3b, and 3b was isolated as a solid stable even in air. Reaction of 3a and 3b with W(CO)5·THF gave the corresponding η1-selenoaldehyde tungsten complexes 4a and 4b, respectively. Some reactions
