ABSORPTION OF CARBON DIOXIDE BY OXO- AND HYDROXOBISMUTH ORGANOMETALLIC DERIVATIVES WITH NEW PHOSPHORUS CONTAINING PENDANT ARM LIGANDS

Project manager: Dr. Albert Soran

Project timespan
2010 (5 months) -- 2011 -- 2012 (7 months)

Abstract
The project has major importance because there is no literature data regarding organometallic bismuth derivatives with phosphorus containing pendant arm(s) on one hand and chemical fixation of CO₂ is of growing interest due to stringent reduction of atmospheric CO₂ concentration, its potential use as C1 source in organic synthesis, and its biological importance on the other hand.

The project has four major objectives:

1. Synthesis and structural characterisation of new phosphorus pendant arm ligands;
2. Synthesis and structural characterisation of mono- and diorganobismuth(III) derivatives using the above mentioned ligands;
3. Synthesis of the oxo- and hydroxo- organobismuth derivatives of type L₂BiOBiL₂, (LBiO)_n (n =1, 2) si L_mBi(OH)_3-m (m = 1, 2);
4. Study on the reactivity of the oxo- and hydroxobismuth derivatives towards CO₂ absorption, and transfer of CO₂ to small organic molecules.

The methods used for the synthesis and structural characterisation of the newly obtained compounds render this project of high complexity. Publishing of the results obtained during the project will increase the project's director international scientific visibility. The estimated results which have potential applications in different areas of chemistry (organic synthesis, environmental chemistry) open new collaboration opportunities with interested institutions and universities.

Project objectives
The general objective of the project is the synthesis of new oxo- and hydroxo- organobismuth(III) derivatives with new phosphorus pendant arm ligands and their use for the absorption of CO₂ . The original research will be conducted on four main directions:

1. Synthesis and structural characterisation of new phosphorus pendant arm ligands;
2. Synthesis and structural characterisation of mono- and diorganobismuth(III) derivatives (LBiCl₂, L₂BiCl) using the above mentioned ligands;
3. Synthesis of the oxo- and hydroxobismuth derivatives of type L₂BiOBiL₂, (LBiO)_n (n =1, 2) si L_mBi(OH)_3-m (m = 1, 2);
4. Study on the reactivity of the oxo- and hydroxoorganobismuth derivatives towards CO₂ absorption, and transfer of CO₂ to small organic molecules.
