This thesis describes synthesis and radiohalogenation of closo-carborane and nido-carborate derivatives for application in nuclide therapy and imaging. The work could be divided in to four sections. In the first section, the synthesis of three boronated DNA-intercalators – 1–(N-9-acridinyl-3-aminopropyl)-para-carborane-12-carboxylic acid hydrogen chloride, 1-[1-(N-9-acridinyl-3-aminopropyl)-para-carborane 12-(3-propyloxi)]-1,3-propanediol, 1-(N-9-acridinyl-3-amino-propyl)-1-ortho-carborane-2-ylmethoxy)1-3-propandiol – for potential use in BNCT, using targeted delivery is described. The second section describes the application of the Heck-reaction to 2-iodo-para-carborane, which has successfully been reacted with a number of styrene derivatives, i.e. para-phenyl, chloro, bromo, nitro, methoxy, and methyl-styrene, to furnish the desired trans-β-2-B-para-carborane)styrene. In the third section, radio-iodination and radio-bromination of closo-carboranes is described. Reaction of the corresponding iodinated carborane, in the presence of palladium catalyst, [125I]iodinated and [76Br]brominated carboranes were obtained in high to excellent yields. Section four describes a method for indirect radiolabelling of antibodies with 76Br. It was shown that NBI, a isothiocyanatobenzene derivative of dodecahydro-7,8-dicarba-nido-undecaborate anion, could be radio-brominated using oxidative conditions. The radio-brominated NBI was thereafter conjugated to anti-HER2 antibody for biological evaluation.
