The preparation of organoelement derivatives of barenes by alkylation (barenylation) of various mercury, silicon germanium, tin, phosphorus, arsenic and antimony halides is described. Attempts to prepare the tetrabarenyltin and tribarenylphosphine compounds failed because of steric hindrance. The increase in size of the arsenic and antimony atoms allowed the tri-substituted compounds to be prepared
investigation of the structure of (methyl- and phenyl- barenyl)mercurybromide and (phenylbarenyl)mercuryiodide has been undertaken. The bond lenghts of the HgBr and HgI bonds of these compounds are unchanged in comparison with those in compounds containing less electron-acceptor radicals. Only in the case of the (phenylbarenyl)mercuryiodide does the intermolecular contact Hg…I decrease (3.29 Å instead
