compound introduction
2-叔丁基呋喃是在2-位被叔丁基取代的呋喃。该叔丁基取代可封闭2位，从而在5位上实现2-叔丁基呋喃的定量功能化。一份报告描述了在TiCl | 4 |存在下，使用2-叔丁基呋喃和其他2-烷基呋喃封端生长的聚异丁烯二苯基碳鎓（PIB | + |）聚合物。 2-tert-Butylfuran is a furan substituted at the 2-position with a tert-butyl group. This t-butyl substitution blocks the 2-position, allowing a quantitative functionalization of 2-tert-Butylfuran at the 5-position. A report describes using 2-tert-Butylfuran and other 2-alkyl furans to cap growing polyisobutenyl diphenylcarbenium (PIB|+|) polymers in the presence of TiCl|4|.
