A solution comprising a reaction product of a magnesium alkoxide with a carboxylic acid halogenide in a hydrocarbon solvent, wherein a dissolved magnesium concentration is at least 0.9 mmol/g and a molar ratio between carboxylic acid halogenide functions and magnesium is at least 0.84:1.
A method for preparing magnesium-containing complex solution comprising reacting a monovalent carboxylic acid halogenide with a magnesium alkoxide in a hydrocarbon solvent at a molar ratio of at least 0.84:1 to 1.8:1.
A method for preparing magnesium-containing complex solution comprising reacting a dicarboxylic acid dihalogenide with a magnesium alkoxide in a hydrocarbon solvent at a molar ratio of at least 0.42:1 to 0.9:1.
