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…
