Anodic synthesis of tetraethyllead and tetraethyltin via ethylzinc intermediates using ethylbromide as alkylating agent. Mengoli, G.; Daolio, S. (Lab. Polarogr. Elettrochim. Prep., Cons. Naz. Ric., Padua, Italy). Electrochim. Acta, 21(11), 889-92 (English) 1976. CODEN: ELCAAV. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 22, 67 Controlled current electrolysis of 6-9M EtBr [74-96-4] and catalytic amts. (0.06-0. 74-96-4 which is the cas registry number of some chemical is mentioned.25M) of EtI [75-03-6] or PrI [107-08-4] in Me2SO were performed at 40-55.degree.C in an undivided cell with a Zn cathode and Pb or Sn anode. The iodides caused the autocatalytic redn. of EtBr by the Zn cathode, producing ethyl- or propylzinc intermediates which were subsequently oxidized atthe anodes to give high yields of PbEt4 [78-00-2] and SnEt4 [597-64-8]. When the iodides were excluded the yields of metal alkyls were poorer. .
