Chemical compoundTemplat:SHORTDESC:Chemical compound

Bromopentakarbonilrenium(I) adalah sebuah senyawa anorganik dari renium dengan rumus kimia Re(CO)₅Br. Senyawa ini umumnya digunakan untuk sintesis kompleks renium lainnya.

Pembuatan

Bromopentakarbonilrenium(I) tersedia secara komersial. Senyawa ini juga murah dan mudah disintesis melalui oksidasi direnium dekakarbonil dengan bromin:^[1]

Re₂(CO)₁₀ + Br₂ → 2 ReBr(CO)₅

Senyawa ini pertama kali dibuat melalui "karbonilasi reduktif" renium(III) bromida:^[2]

ReBr₃ + 2 Cu + 5 CO → BrRe(CO)₅ + 2 CuBr

Tembaga(I) bromida merupakan produk sampingannya.

Reaksi

Bromopentakarbonilrenium(I) merupakan prekursor kompleks renium lainnya. Senyawa ini akan bereaksi dengan seng dan asam asetat menghasilkan pentakarbonilhidridorenium (HRe(CO)₅).^[3]

Re(CO)₅Br + Zn + HO₂CCH₃ → ReH(CO)₅ + ZnBrO₂CCH₃

Senyawa ini juga bereaksi dengan tetraetilamonium bromida dalam diglima menghasilkan [NEt₄]₂[ReBr₃(CO)₃)], suatu prekursor penting bagi senyawa yang mengandung fragmen renium trikarbonil.^[4]

Pemanasan bromopentakarbonilrenium(I) dalam air akan menghasilkan kompleks triakuo:

ReBr(CO)₅ + 3 H₂O → [Re(H₂O)₃(CO)₃]Br + 2 CO

Rute ini menghindari pembentukan produk sampingan tetraetilamonium bromida, yang seringkali sulit dihilangkan dari campuran reaksi.^[5]
