The Indian Review June 1953

1933

The second method was the ring-closure of the keto ester (V) which was prepared by the action of zinc methyliodide on the acid chloride of ethyl hydrogen 3.-rnethylcyciopentane-1 :i-disoetate.258 R. D. DESAI Though the method involved a number of stages the yield of the dione (IV) was so good that it could be recommended for its prepration. [...] The slightly acidic solution was heated on a sand-bath till the evolution of carbon dioxide ceased and the dione crystallised from the strongly acid solution on cooling. [...] The formtion of butyric acid indicates the presence of a side chain of at least 4 carbon atoms in the lignin molecule. [...] The mixture was then warmed cautiously with a little alcohol and the sweet pineapple odour of the butyric ester confirmed the acid. [...] All these point to the fact that iridium chloride in solution is first reduced and then reacts with the sulphide present ; the presence of a small amount of chlorine in solution cannot prevent the reduction.
