摘要:
A method for producing an anionized meso-form double-cross-linked ligand represented by formula (3), including: bringing a compound represented by formula (1) into contact with a compound represented by formula (2) at -25°C or less; and introducing an anionizing agent within 5 hours after the contact, wherein R 1 to R 10 are independently a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms, or the like; A and A' are independently a cross-linking group containing an atom belonging to the 14 th group of the periodic table; M and M' are independently an atom belonging to the 1 st or the 2 nd group of the periodic table.
摘要:
A process for preparing a cyclic organosilane using a solvent that promotes ring-closure reactions between an organosilane compound and a dihalo organic compound is disclosed. The ring-closure reactions may form a 4-, 5- or 6-member cyclic organosilane. The process involves a mixture including a dihalo organic compound, an organosilane having at least two functional groups, a solvent and magnesium (Mg). The two functional groups in the organosilane may include halogen, alkoxy or a combination thereof. In the presence of Mg, a Grignard intermediate is formed from the dihalo organic compound in the mixture. The solvent favors intra-molecular or self-coupling reactions of the Grignard intermediate. The intra-molecular or self-coupling reaction promotes ring-closure reaction of the Grignard intermediate to form the cyclic organosilane.
