六（2，4，6-三异丙基苯基）四硅杂环丁烷与马来酸酐（3）反应生成2，9-二氧杂-5，6，7，8-四硅杂四环癸烷-3-酮衍生物4，推测是通过两个连续的[2 + 2]环加成反应。四（2，4，6-三异丙基苯基）二硅烯与3反应，经[2 + 3]环加成和1，2-氢转移，得到双环1，2-二氢呋喃并[3，2-d][1，2，3]恶二硅醇-5（6 H）-酮衍生物5。4和5的结构通过X射线晶体学测定。
The reaction of hexakis(2,4,6-triisopropylphenyl)tetrasilabutadiene with maleic anhydride (3) furnishes the 2,9-dioxa-5,6,7,8-tetrasilatetracyclodecan-3-one derivative 4, presumably by a sequence of two consecutive [2 + 2] cycloadditions. Tetrakis(2,4,6-triisopropylphenyl)disilene reacts with 3 to afford the bicyclic 1,2-dihydrofuro[3,2-d][1,2,3]oxadisilol-5(6H)-one derivative 5 via a formal [2 + 3] cycloaddition and a 1,2-hydrogen shift. The structures of 4 and 5 were determined by X-ray crystallography.
