Spectroscopic (IR, .C, and UV-Vis) properties of the salts are summarized. The reactivities, structures, properties, characteristics and applications of each salt are discussed in detail for the salts of most elements (except for carbon).作者: bisphosphonate 時間: 2025-3-26 05:55
Thio-, Seleno-, Telluro-Amides, leading to other thioamides are also presented. The discussion focuses on synthetic methods for selenoamides starting from amides, and functional group manipulations of selenoamides leading to functionalized selenoamides. The review ends with some examples of how to synthesize telluroamides.作者: Axillary 時間: 2025-3-26 08:49
