 
 <prompt> Wetin dey work together to create D3h molecular symmetry? Given the previous question, write a context wey contain the answer. E fit be 1 - 20 sentences. Context: <response>: ```Dey plenty important organozinc compounds wey dey ground. Organozinc chemistry na di science of organozinc compounds wey dey describe dia physical properties, how dem dey synthesize and how dem dey react. One important application na di Frankland-Duppa Reaction wey involve oxalate ester wey dey react with alkyl halide, zinc and hydrochloric acid to form α-hydroxycarboxylic esters. Another one na di Reformatskii reaction wey dey convert α-halo-esters and aldehydes to β-hydroxy-esters. Simmons–Smith reaction dey involve carbenoid wey dey react with alkene or alkyne to form cyclopropane. Barbier reaction na zinc version of Grignard reaction and e better pass am. Organozinc compounds no too dey reactive like Grignards, dem dey expensive and hard to handle. Some commercial organozinc compounds na dimethylzinc, diethylzinc and diphenylzinc. For one study, dem get active organozinc compound from cheaper organobromine precursors.```
