The synthesis of the pentacarbonylchromium complex [{2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 }(Cl)SnCr(CO) 5 ] is reported. Starting with this compound, organotin(II)pentacarbonylchromium methoxide [{2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 }(OMe)SnCr(CO) 5 ] was prepared and used for the synthesis of dimeric N→Sn intramolecularly coordinated organotin(II)pentacarbonylchromium hydroxide [{2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 }Sn(μ‐OH)Cr(CO) 5 ] 2 by easy hydrolytic protocol. In addition, acid–base‐type reaction of this latter compound with HOTf provided unprecedented cyclization product [6‐(Me 2 NCH 2 )‐2,3‐(C 6 H 3 CH 2 OSn)Cr(CO) 5 ] 2 . The cyclization process is accompanied by the formation of a new C–O covalent bond along with the elimination of Me 2 NH.
