四唑类化合物的研究已有一百多年的历史，应用领域十分广泛。几年前，Sharpless和他的同事报道了一种在水中用锌盐作为催化剂制备5-取代的1H-四唑的环境友好方法。为了揭示锌盐在该反应中的确切作用，研究了一系列旨在捕获和表征固体中间体的水热反应。本研究使我们能够获得无数有趣的金属-有机配位聚合物，不仅部分显示了金属物种在四唑化合物合成中的作用，而且还提供了一类显示有趣的化学和物理性质的配合物，如二次谐波产生（SHG），荧光，铁电和介电行为。在本教程中，我们将主要集中在原位水热法合成的四唑配合物。首先，我们将讨论这些化合物的合成和晶体结构。本文将介绍四唑配合物的各种性质及其在有机合成中的应用。最后，我们将概述在这一化学领域的一些期望。四唑类化合物与金属离子的直接配位化学以及叠氮锡与有机氰基的环加成反应原位合成四唑类化合物的研究在本文中不予讨论。
Tetrazole compounds have been studied for more than one hundred years and applied in various areas. Several years ago Sharpless and his co-workers reported an environmentally friendly process for the preparation of 5-substituted 1H-tetrazoles in water with zinc salt as catalysts. To reveal the exact role of the zinc salt in this reaction, a series of hydrothermal reactions aimed at trapping and characterizing the solid intermediates were investigated. This study allowed us to obtain a myriad interesting metal-organic coordination polymers that not only partially showed the role of the metal species in the synthesis of tetrazole compounds but also provided a class of complexes displaying interesting chemical and physical properties such as second harmonic generation (SHG), fluorescence, ferroelectric and dielectric behaviors. In this tutorial review, we will mainly focus on tetrazole coordination compounds synthesized by in situ hydrothermal methods. First, we will discuss the synthesis and crystal structures of these compounds. Their various properties will be mentioned and we will show the applications of tetrazole coordination compounds in organic synthesis. Finally, we will outline some expectations in this area of chemistry. The direct coordination chemistry of tetrazoles to metal ions and in situ synthesis of tetrazole through cycloaddition between organotin azide and organic cyano group will be not discussed in this review.
