Various neutral, mono- and dicationic halogen bond donors were screened for their ability to act as catalysts in a Nazarov cyclisation reaction. Using a highly preorganized dicationic catalyst with a noncoordinating counterion proved essential for high activity.
筛选了各种中性、单阳离子和双阳离子卤素键供体，以考察它们在纳扎罗夫环化反应中作为催化剂的能力。事实证明，使用具有非配位抗衡离子的高度预组织双阳离子催化剂对于高活性至关重要。
