During this study, an easy procedure is presented for the preparation of a new nickel ion-containing DABCO based ionic liquid. The prepared reagent was characterized using FT-IR, FESEM, EDX, XRD, ICP-OES, TGA and DRS analyses. In continue the catalytic activity of this reagent which is formulated as [C 4 (DABCO) 2 ].NiCl 4 was investigated in the reduction of a variety of carbonyl compounds to their corresponding alcohols with NaBH 4 . The promoting ability of this catalyst was also confirmed in the acetylation of alcohols with CH 3 COCl. All reactions were carried out in short times with high to excellent yields. The catalyst was also recoverable and reusable in the studied reactions.
