Phenols are 2,6-divinylated by treatment with ethyne at 100 °C in
chlorobenzene in the presence of SnCl
4
–Bu
3
N,
the divinylation occurring predominantly to exclusively with phenol,
alkylphenols and alkoxyphenols; an appropriate amount of the tin reagent
and the correct reaction temperature are essential for the
divinylation.
在 SnCl 4 -Bu 3 N 的存在下,在 100 °C 的氯苯中用乙炔处理苯酚,可使苯酚发生 2,6-二乙烯基化,二乙烯基化主要或完全发生在苯酚、烷基酚和烷氧基苯酚中;适量的锡试剂和正确的反应温度对二乙烯基化至关重要。
