Novel carboranyl amines [7-NH2(CH2)nS-7,8-C2B9H11]â were synthesized by alkylation of 1-mercapto-ortho-carborane with Ï-bromoalkylphthalimides followed by removal of the protecting group with hydrazine. closo-Carboranyl azides 1-N3(CH2)nS-1,2-C2B10H11 were prepared by the reaction of the corresponding carboranyl alcohol/iodide with sodium azide and converted to the water soluble nido-form [7-N3(CH2)nS-7,8-C2B9H11]â with ammonium formate in refluxing methanol.
通过将 1-巯基正
