Using ortho-bis(porpargyl alcohol) derivatives as starting materials, we employed sulfenyl or sulfinyl chloride under base condition to generate bis-allene intermediates. 所采用的合成方式以邻位二丙炔醇为起始物，在碱性环境中与次磺氯或亚磺氯作用生成丙二烯后，再经环化反应得多并苯化合物。
A sulfenic acid is an organosulfur compound and oxoacid with the general formula RSOH, where R≠H. It is the first member of the family of organosulfur oxoacids, which also include sulfinic acids and sulfonic acids, RSO2H and RSO3H, respectively.
