Also in the presence of functional groups , the 2 + 2 cyclization of 1 and 2 to give thiocrown ethers 3 is achieved in good yields, if B(O i Pr) 3 /Al(O i Pr) 3 ) is present. Furthermore a sandwich‐like cationic complex [Ag 4 ‐( 3b ) 2 ] 4+ was prepared with 3b . This complex is also stable in solution.
