Abstract Friedel-Crafts acylation reaction of ferrocene with carborane carboxylic acid chlorides was shown to be a facile and convenient route for the preparation of carboranyl ferrocenyl oxo-derivatives in high yield. Compounds thus obtained were easily transformed into the corresponding alcohols using lithium aluminum hydride whereas their conversion into the corresponding ferrocenylalkyl carboranes

of 5-substituted carborane tetrazoles was synthesized by acylation of 5-phenyl-1-H-tetrazole with the available o- and m-carborane carboxylic acid chlorides or o- and m-carborane acetic acid chlorides in the presence of pyridine. Successive thermolysis of the carborane tetrazoles in toluene followed by the extrusion of nitrogen resulted in a series of previously unknown carborane 1,3,4-oxadiazoles

Amides, amines, and alcohols were synthesized from 9-o- and 9-m-carboranecarboxylic chlorides. It follows from comparison of the H-1 NMR spectra of N,N-dimethyl-1-o- and -1-m-carboranecarboxamides and N,N-dimethyl-9-o- and -9-m-carboranecarboxamides that pi-bonding of the carborane polyhedron with the carbonyl group in 1-carboranyl dimethylamides is stronger than that in 9-carboranyl diethylamides. Oxidation of 9-hydroxymethyl-m-carborane with pyridinium chlorochromate gives 9-m-carboranylmethyl 9-m-carboranecarboxylate.
