Abstract A series of new nido-carborane based carboxylic acids 10-HOOC(CH2)n(Me)S-7,8-C2B9H11 (n = 1–4) was prepared by alkylation of tetrabutylammonium salt of 10-methylthio-7,8-dicarba-nido-caborane with ω-halogenoalkyl esters or nitriles followed by acid hydrolysis.

Abstract A series of new nido-carborane based carboxylic acids 10-HOOC(CH2)n(Me)S-7,8-C2B9H11 (n = 1–4) was prepared by alkylation of tetrabutylammonium salt of 10-methylthio-7,8-dicarba-nido-caborane with ω-halogenoalkyl esters or nitriles followed by acid hydrolysis. Likewise nido-carborane based amines 10-H2N(CH2)n(Me)S-7,8-C2B9H11 (n = 2, 3) were obtained using ω-bromoalkylphthalimides as alkylating agents followed by removal of the protecting group with hydrazine. Structure of 10-C6H4(CO)2NCH2CH2(Me)S-7,8-C2B9H11 was determined by single crystal X-ray diffraction.
