“…Noting the structural similarity between 1,4-cis,cisdilithiobutadiene (j) and o,o'-dilithiobiphenyl, we postulated a doubly bridged structure Z! : for the latter compound (21,23). MNDO calculations supported this suggestion (23), but the molecule is too large for an ab initio examination.…”

“…[16a] 2,2Ј-diiodobiphenyl, [19] and (Z)-1-iodo-2-(1-iodo-1-phenylhex-1-en-2-yl) benzene [20] were prepared according to literature procedures. Other materials were commercially available and were used without further purification.…”

“…Hier berichten wir über die Synthese funktionalisierter Benzylmagnesiumreagentien unter Verwendung einer neuen S/Mg-Austauschreaktion. [2,3] Wir wählten funktionalisierte benzylische o-(o-Iodphenyl)phenylthioderivate [4] 1, die sich ausgehend von 2,2'-Diiodbiphenyl [5,6] (4) leicht durch Reaktion von Thiosulfonaten 2 mit dem entsprechenden Monomagnesiumderivat 3 herstellen ließen (Schema 1). Die benötigten Thiosulfonate 2 wurden sowohl durch Reaktion von PhSO 2 Na mit Disulfiden [7] als auch durch Reaktion von PhSO 2 SNa mit zahlreichen Benzylhalogeniden in DMF hergestellt; [8] siehe Hintergrundinformationen.…”
