(2018-11-29)Organoantimony(V) compounds are potent Lewis acids which have been used for the complexation of anions or for the catalysis of organic reactions. Inspired by the broad range of applications developed for the stable Group ...
-
(2016-06-30)It is known that SbF5 and SbCl5 are highly robust and show stronger acidic behavior than their boron counterparts, BF3 and BCl3, respectively. This effect is caused by the polarizability and the electropositivity of these ...
-
(2017-03-31)The design of molecular chemical sensors has generally relied on the use of colored and/or luminescent organic dyes or transition metal complexes; however, recent advances have been made in the use of heavy main group ...
-
(Texas A&M University, 2005-11-01)The primary goal of the research described in this thesis concern the synthesis, characterization and study of 1,8-bis(diarylmethylium)naphthalenediyl dications. Such dications have been prepared from the corresponding ...

Tin, Antimony, Bismuth, and Tellurium Lewis Acids in sigma-Accepting Ligands for Transition Metals (2012-10-19)The interactions between ligands and transition metals have been an essential subject in inorganic chemistry. Other than the commonly known L-type (two-electron donors) and X-type ligands (one-electron donors), Z-type ...
