Abstract A new kind of Mannich-type reaction involving an intramolecular catalysis mechanism was applied for the synthesis of α-aminogermyl phosphonic esters. It was found that the carbonyl group was activated by the coordination between the oxygen atom and the germanium atom. Different amines were investigated under the same reaction conditions. The structures of the products were determined by 1H
摘要 一种涉及分子内催化机制的新型曼尼希反应用于合成α-氨基锗烷基膦酸酯。发现羰基被氧原子和锗原子的配位活化。在相同的反应条件下研究了不同的胺。产物的结构通过1H、31P NMR、IR光谱和元素分析确定。
