| | 1-Chloromethyl naphthalene Usage And Synthesis |
| Chemical Properties | Solid | | Uses | 1-(Chloromethyl)naphthalene is a key material for synthesis dye pigment and as fluorescent brightening agent. It is employed in synthetic resin and medicine. Palladium-catalyzed nucleophilic dearomatization of chloromethyl naphthalene derivatives produce ortho- or para-substituted carbocycles in satisfactory to excellent yields. | | General Description | Kinetics and dissociation mechanism of 1-(chloromethyl)naphthalene following 266nm photoexcitation has been studied. Intermolecular nucleophilic dearomatization of 1-chloromethyl naphthalene with various activated methylene compounds has been investigated. | | Synthesis | step A, uniformly mixing
naphthalene, paraformaldehyde, Lewis acid, a phase transfer catalyst
and a hydrochloric acid solution with the mass concentration of 42-43%,
carrying out heat preservation reaction, standing, separating liquid,
and washing an oil phase to obtain a 1-chloromethyl naphthalene crude
product; the Lewis acid is a mixture of ferric chloride and copper
chloride with a molar ratio of 1: 0.5-1;
step B, adding the
1-chloromethyl naphthalene crude product into an alcohol solvent,
heating to dissolve the crude product, cooling to crystallize,
filtering, washing and drying to obtain a 1-chloromethyl naphthalene
product; |
