A NEW SERIES OF ORGANOBORANES. VIII. THE REACTION OF PHOSGENE WITH THE DILITHIUM SALTS OF O- AND M-CARBORANE.
Abstract
When phosgene was reacted with o-B10H10C2Li2 to generate, desired type of compound, the heterocycle (o-B10H10C2.CO)2 was obtained as a high melting solid (m.p. 315) in 50% yield. The carbonyl stretching frequency appeared as a single sharp band at 1720/cm. which indicates a planar ring configuration. In the analogous reaction between m-B10H10C2Li2 and phosgene, employment of a large excess of COC12 produced the diacid dichloride, m-B10H10C2(CO.C1)2, which could be expected from this reaction but was obtained in only 20% yield. The other products isolated consisted of a pentane soluble highly viscous material and a pentane insoluble solid, both of which were found to be polymeric (with 3 and 5 repeating units). When equimolar amounts of the two reactants were allowed to interact, only traces of the diacid dichloride were isolated. However, again the polymer having five repeating units proved to be the product with the highest molecular weight.
