Isoselenocarbonyl complexes.

Area of Science:

• Organometallic Chemistry
• Coordination Chemistry
• Main Group Chemistry

Background:

• The synthesis of metal-containing heterocumulenes is a developing area.
• Isoselenocarbonyl complexes are of interest due to their unique bonding and reactivity.

Purpose of the Study:

• To investigate the salt elimination reactions of [NEt4][Mo(CSe)(CO)2(Tp*)] with metal halide complexes.
• To synthesize and characterize novel isoselenocarbonyl complexes.

Main Methods:

• Salt elimination reactions.
• Reactions with metal halide complexes including ruthenium and iron.
• Structural characterization using X-ray crystallography.
• Spectroscopic and microanalytical data analysis.

Main Results:

• Synthesis of molybdenum-ruthenium derivatives [Mo{CSeRu(L)2(η-C5R5)}(CO)2(Tp*)] (L = PPh3, R = H 4; L = CO, R = Me 5).
• Synthesis of molybdenum-iron derivative [Mo{CSeFe(CO)2(η-C5H5)}(CO)2(Tp*)] (6).
• Structural characterization of two molybdenum-ruthenium derivatives and one hydrido-isoselenocarbonyl complex [Mo{CSeRuH(CO)2(PPh3)2}(CO)2(Tp*)] (7).

Conclusions:

• Salt elimination reactions provide a viable route to novel isoselenocarbonyl complexes.
• The synthesized complexes demonstrate the versatility of the [Mo(CSe)(CO)2(Tp*)] precursor.
• Further investigation into the reactivity of these complexes is warranted.
