Electroless copper coating solutions. Murakami, Kanji; Kawamoto, Mineo; Wajima, Motoyo; Morishita, Hirosada (Hitachi, Ltd., Japan). Japan. Kokai JP 52021226 17 Feb 1977 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C23C003-02. APPLICATION: JP 75-97551 13 Aug 1975. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) The electroless Cu coating solns. contain Cu(II) salt, Cu complexing agent, Cu reducing agent, NaOH, and .gtoreq.1 allyl alc. and its derivs. The soln. forms a soft Cu film. Thus, a Cu coating was made on a stainless steel substrate in an aq. soln. contg. CuSO4.5H2O 3 g/L, EDTA 10 g/L, 37% HCHO 3 mL, .beta.-chloroallyl alc. [5976-47-6] 0.03 g/L, and NaOH to give a pH of 12. The Cu film had an elongation of 4%.

DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) The tetraphosphine all-cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane (Tedicyp) in combination with [Pd(C3H5)Cl]2 affords an efficient catalyst of the coupling of 2-chloroacrylonitrile with aryl boronic acids. In the presence of 1% catalyst, the 2-arylacrylonitrile derivs.Several substances with their cas registry numbers 5976-47-6 and 918788-83-7 may be metioned in this study. were obtained in medium to good yields. A variety of substituents such as alkyl, methoxy, fluoro, trifluoromethyl, formyl, or nitro on the aryl boronic acid are tolerated. The cross-coupling reactions of Me 2-chloroacrylate with aryl boronic acids give simple access to 2-phenylacrylate derivs., which are useful precursors for the synthesis of biol. active compds. such as ibuprofen, ketoprofen, and naproxen. .
