Diamondoid Hydrazones and Hydrazides: Sterically Demanding Ligands for Sn/S Cluster Design
摘要:
A series of new adamantane and diamantane hydrazides was synthesized and coupled with organo-functionalized Sn/S clusters of the general type [(RSn4S6)-Sn-I] (R-I = CMe2CH2COMe) to form diamondoid-decorated Sn/S dusters. The new ligand precursors as well as the resulting hybrid compounds were analyzed by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction, and first insights were gained in the installation of sterically highly demanding and at the same time rigid mono-, di-, and trifunctionalized diamondoid ligands on tetrelchalcogenide cages.
