Abstract: This coated metal plate is a chromate-free coated metal plate for exterior applications, which comprises a metal plate and a coating film that is arranged on the metal plate. The coating film contains 0.2-15 vol % of porous particles as a gloss control agent, and contains 0.2-15 vol % of primary particles as a matting agent. If R1 (?m) is the number average particle diameter of the gloss control agent, R2 (?m) is the number average particle diameter of the matting agent, T (?m) is the film thickness of the coating film, ?1 (?m) is the standard deviation of the number-based particle size distribution of the gloss control agent and ?2 (?m) is the standard deviation of the number-based particle size distribution of the matting agent, the coated metal plate satisfies the following formulae.

Abstract: A catalyst composition for a cross-coupling reaction comprising a nickel metal source, a fluorine source, and a nitrogen-containing heterocyclic compound having a specific structure, or a phosphine compound. Using this catalyst composition, a cross-coupled compound R5—R6 (wherein R5 and R6 are an aryl or heteroaryl group, or a linear, branched or cyclic alkyl group or a linear, branched or cyclic alkenyl group) is produced with a high selectivity by allowing an organometallic compound of the formula (2) R5-MY1 or the formula (3) R5-M-R5 (wherein R5 is the same as defined above, M is a Mg or Zn atom, and Y1 is a halogen atom) to react with a compound of the formula (4) R6—Y2 (wherein R6 is the same as defined above, and Y2 is a halogen atom, a methanesulfonate group, a toluenesulfonate group or a trifluoromethanesulfonate group).

Abstract: A catalyst composition for a cross-coupling reaction comprising a nickel salt-amine complex of formula (1), and triphenylphosphine. where R1 thru R4 independently represent alkyl, aryl, heteroaryl or alkenyl; n is an integer of 1-6; and X independently represents halo, hydroxyl, nitrate or acetate group. Using the catalyst composition, a cross-coupling reaction is carried out between a boron-containing compound of formula (2) and a compound of formula (3). where R5 and R6 are the same as R1-R4 defined above; Y independently represents hydroxyl or alkoxy, Z is halo, methanesulfonate or trifluoromethanesulfonate.

Abstract: A paint composition containing a corrosion inhibitor A prepared from porous silica particles, to which Ca ion is bonded by ion-exchange, and a polyphosphate B preferably at an A/B weight ratio of 60/40 to 5/95 and at an A+B ratio of 5-150 parts by weight based on 100 parts by weight of resinous components. A base metal sheet is preferably one pre-treated with a chemical agent containing at least one fluoroacid. Since the polyphosphate B controls dissolution of Ca ion, an effect of Ca ion on corrosion inhibition is maintained over a long term. The painted metal sheet does not put harmful influences on the environment, since it does not contain chromium compounds.
