A series of halomethyl cations was prepared and studied by 13C NMR spectroscopy. Their structures and 13C NMR chemical shifts were also calculated by ab initio/DFT/GIAO-MP2 methods. The δ13C of trihalomethyl cations CX3+ (X = Cl, Br, I) and dimethyl

Comparison of ab initio/IGLO calculated 1 H, 13 C, and 29 Si NMR chemical shifts with the experimental data on trimethylsilyl perchlorate and related derivatives supports the conclusions that no long-lived persistent trimethylsilicenium ion has been

/sup 29/Si and /sup 35/Cl NMR spectroscopic and X-ray crystallographic study of triphenylsilyl perchlorate shows it to be a covalent perchloryl ester in both solution and the solid state. The results are in accord with earlier studies notably those o
