  摘要：

  A series of tetrakis(bromoalkyl)methanes was synthesized and characterized. The tetrakis(3-bromopropyl)methane was chosen as ideal core to cascade polymers, since it undergoes facile substitution with bulky nucleophiles, denoting the need for at least three carbon atoms between the quaternary center and the leaving group to circumvent major steric problems caused by the core carbon. The readily available 4-nitro-4-(3-hydroxypropyl)-1,7-heptanediol was used to afford a novel entry to tetrakis(3-bromopropyl)methane as well as other building blocks to cascade polymers.
