我们证明了苯桥联的双炔丙醇与氯代二烷基膦的反应通过1，2-双（α-氧膦基联烯基）苯的[2+2]环加成反应只生成3，8-双（二烷基氧膦基）萘并[B]环丁烯。还实现了产物的脱膦化。(c)2006爱思唯尔有限公司保留所有权利。
We have demonstrated that the reaction of benzene-bridged bis(propargyl alcohol)s with chlorodialkylphosphines exclusively afforded 3,8-bis(dialkylphosphinyl)naphtho[b]cyclobutenes via the [2+2] cycloaddition of 1,2-bis(alpha-phosphinylallenyl)benzenes. Dephosphinylation of the product has also been achieved. (c) 2006 Elsevier Ltd. All rights reserved.
