Under the mediation of transitionmetal carbonyls, cycloaddition of 3-t-butyl-1,1,2,2-tetrafluoro,2-disilacyclobutane (1) to various cyclic dienes have been studied under photochemical conditions. For conjugates dienes, Ni and Co mediated reactions give 1,4-addition products, whereas Fe, Mo and W mediated reactions result in 1,2-addition products. The hard metal Cr mediates the reactions to give products
