BIS(BICYCLO(2.2.1)HEPTA-2,5-DIENE)-RHODIUM(I) PERCHLORATE Chemical Properties,Usage,Production

Uses

Bis(bicyclo[2.2.1]hepta-2,5-diene)rhodium Perchlorate is a precursor for various cationic rhodium complexes, which are used as catalysts for hydrogenation, allylic hydrogen migration, hydrosilation, and hydroacylation.

Preparation

Preparative Methods of Bis(bicyclo[2.2.1]hepta-2,5-diene)rhodium Perchlorate: to a mixture of bicyclo[2.2.1]hepta-2,5-diene (nbd, 0.14 g, 1.5 mmol) and Bis(bicyclo[2.2.1]hepta-2,5-diene)dichlorodirhodium (0.35 g, 0.75 mmol) in CH2Cl2 (15 mL) at room temperature is added Silver(I) Perchlorate (0.315 g, 1.5 mmol) under nitrogen. After stirring for 1 h, precipitated AgCl is filtered off to give a CH2Cl2 solution of [Rh(nbd)2]ClO4. This solution can be directly used for the next reaction^[1], or diluted by THF (15 mL) followed by evaporation of CH2Cl2 under vacuum to separate orange needles of [Rh(nbd)2]ClO4, which are collected and washed with cold THF and then dried in vacuo to afford rust-brown crystals (0.5 g)^[2].

storage

Bis(bicyclo[2.2.1]hepta-2,5-diene)rhodium Perchlorate can explode when heated.
