Abstract
1,2,3,4-Tetramethyl-1,4-diboracyclohex-2-ene (1) reacts in THF solution with two equivalents of potassium metal to yield a red solution of the dianion 12-. Reactions of 1·2 K with allylnickel bromide dimer, cyclooctadiene-rhodium chloride dimer or bis(ethene)rhodium chloride dimer give the triple-deckers 3, 4, and 5, respectively. The constitution of the diamagnetic (30 VE) triple-deckers is derived from NMR and MS data.Keywords
