The reactions of trisSnBr 3 ( 1 ) [tris = (Me 3 Si) 3 C] and n BuSnCl 3 with Na 2 X (X = O, S, Se) yield the heterocyclic adamantanes 2 – 6 . The reaction of 1 with Na 2 O is carried out in liquid ammonia under normal pressure at –78 °C to give (trisSn) 4 O 6 ( 2 ). However, the reaction of 1 with Na 2 S and Na 2 Se under pressure at room temperature results in the formation of (trisSn) 4 S 6 ( 3 ) and (trisSn) 4 Se 6 ( 4 ). n BuSnCl 3 reacts with Na 2 S and Na 2 Se in liquid ammonia at –33 °C under normal pressure to give ( n BuSn) 4 S 6 ( 5 ) and ( n BuSn) 4 Se 6 ( 6 ), respectively.
