Heechung Yang, John E. Reardon, 1 and Perry A. Frey** abstract: Derivatives of heptakis [4, 4', 4"-phosphinidynetris (benzenemethanamine)] undecagold, 1, molecular formula Au11 (CN) 3 [P (C6H4CH2NH3)] 7, are described. These include undecagold complexes with a single free primary aminogroup, a single bromoacetyl group, and a single maleimido group per molecule. Hydrolysis of mono (7V-phthalyl) icosa (iV-acetyl)-l at pH 3.2 and 46 C under anaerobic conditions and in the presence of NaBH3CN produces icosa (7V-acetyl)-l. Partial acylation of 1 with 1.3 equiv of 2, 3-dimethylmaleic anhydride followed by complete acetylation with acetic anhydride pro-duces a mixture consisting largely of mono- and bis (di-
