allene

A account summary on new achievement about synthesis and theory of compounds with lone multiple bonds and heavy allenes and cumulenes in ⅣA group is given.

概括总结了ⅣA族重元素孤立双键化合、丙烯型分子和环丙烯型分子合成及理论研究新成果。

Using ortho-bis(porpargyl alcohol) derivatives as starting materials, we employed sulfenyl or sulfinyl chloride under base condition to generate bis-allene intermediates.

所采用合成式以邻位二丙炔醇为，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。
