Abstract
Di-tert-butylsilylene, generated by photolysis of hexa-tert-butylcyclo trisilane, reacts with selenophene or 2,5-dimethyltellurophene by chal cogen abstraction to furnish the 1,3-diselena-2,4-disiletane 6 and 1,3 -ditellura-2,4-disiletane 7 ring systems. The X-ray structure analyses of 6 and 7 reveal strictly planar four-membered rings with the smalle r endocyclic angles at the chalcogen and the larger angles at the sili con atoms.
