M lithium perchlorate under sonication. Under these reaction conditions, the cycloaddition to quadricyclane, 1-methoxy-, 1- and 2-trimethylsilyloxy-1,3-butadiene and to the Danishefsky diene were investigated. In the cycloaddition to 1-trimethylsilyloxy-1,3-butadiene and to the Danishefsky diene the open chain adducts (Z)- 14 and 17 were obtained in high yield as primary adducts. Eventually, the former
