Properties of Chalcogen–Chalcogen Bonds, XV 1) . ‐ Lithium 2,4,6‐Tri‐ tert ‐butylphenylselenide: Synthesis, Structure, and Reactions with Formation of Se – P, Se – C, Se – Si, Se – Sn, and Se – Au Bonds Bis(2,4,6‐tri‐ tert ‐butylphenyl)diselenide ( 1 ) is reduced by lithium triethylhydridoborate to give lithium 2,4,6‐tri‐ tert ‐butyl‐phenylselenide ( 2 ) in high yield. 2 crystallizes with three molecules of tetrahydrofuran coordinated to lithium ([ 2 (THF) 3 ] 2a , space group P &1macr; Z = 4 ). The monomeric compound 2a contains four‐coordinate lithium bonded to two‐coordinate selenium. 2 (LiSeR) reacts with the nonmetal and metal halides t Bu 2 PCl, CH 2 Cl 2 , Me 3 SiCl, Me 3 SnCl, and Ph 3 PAuCl to give t Bu 2 PSeR ( 3 ), RSeCH 2 Cl ( 4 ), (RSe) 2 CH 2 ( 5 ), Me 3 SiSeR ( 6 ), Me 3 SnSeR ( 7 ), and the novel gold( I ) selenophenolate derivative Ph 3 PAuSeR ( 8 )(R = 2,4,6‐tri‐ tert ‐butylphenyl).
