| It is only in recent years that significant progress has been made in the chemistry of supercarboranes. Carbon-atoms-adjacent (CAd) 13- and 14-vertex carboranes and their corresponding 14- and 15-vertex metallacarboranes have been successfully prepared and structurally characterized. Such a breakthrough relies on the use of CAd carborane anions as starting materials. The methodology for the controlled syntheses of CAd nido-carboranes and arachno-carboranes developed earlier in our laboratory provides a very important entry point to supercarboranes. It is very clear that the short C,C'-linkage can force the two cage carbon atoms of carboranes in adjacent positions during the reductive process. Is such a linkage necessary to stabilize the supercarboranes? The answers will be discussed in this talk. |
