Herstellung einiger styrolderivate mit ungesättigten substituenten in p‐stellung

Abstract

p‐Butenylstyrol, p‐äthinylstyrol und p‐Vinylphenylallen wurden hergestellt. Ebenso wurde das p‐Allylstyrol nach einem neuen Verfahren in guter Ausbeute erhalten. Die Styrolderivate wurden homopolymerisiert und mit Styrol copolymerisiert.

Preparation of Soluble Polymeric Supports with a Functional Group for Liquid-Phase Organic Synthesis

“…The polydispersity is good for most of the samples (1,(6)(7)(8)(9)(10)(11)13). The yields range between 20% and 55% and, in most cases, the loading is not dependent on the nature of the functional group.…”

“…Apart from the sample containing a primary amine 7, the average molecular weight of the synthesized copolymers is in the same range as the molecular weight of the reference sample 1. The polydispersity is good for most of the samples (1,(6)(7)(8)(9)(10)(11)13). The yields range between 20% and 55% and, in most cases, the loading is not dependent on the nature of the functional group.…”

“…Various functional groups can be easily introduced onto a styrene, by some well-known organic reactions. According to the literature, 4-vinylbenzylalcohol, 9 4-vinylbenzylamine, 10 but-3-enyl-4-vinylbenzene, 11 4-vinylbenzoic acid, 12 the styrenic monomer bearing the Wang linker 13 and isopropyl 4-styrenesulfonate 14 have been prepared as reported. 4-Vinylbenzyl azide 2 has been synthesized by nucleophilic substitution of 4-vinylbenzylchloride with sodium azide, in dimethylsulfoxide, at 80 °C.…”
