Using this procedure, other diamines such as benzidine and dianisidine may be diazotized and coupled with other amino-naphthols, such as S acid (i-amino-8-naphthol-4-sulfonic acid), J add (2-amino-5-naphthol-7-sulfonic add). Gamma add (2-amino-8-naphthol-6-sulfonic add), and H add (i-amino-8-naphthol-3,6-disulfonic acid), or with simple naphthols such as NW add (i-naphthol-4-sulfonic add), Schaeffer s add (2-naph-thol-6-sulfonic acid), and R add (2-naphthol 3,6-disulfonic add). The procediue would be varied only in the manner of salting out the dyes, each of which would require a set of optimum cond tions... 

Intermolecular oxidative addition of H—C usually involves activated H—C bonds. The weak acid HCN reacts with transition-metal complexes e.g., HCN and NiL lead to the hydride complexes HNi(CN)Lj (L = various phosphorus ligands). The versatile complex IrCl(CO)(PPh3)j adds HCN cleanly in CH Clj at RT to form HIr(CN)(Cl(PPhj)2. The zero-valent complexes Pt(PPhj) or Pt(PPh3)3 also add HCN to yield HPt(CN)(PPh3)j. Reactions of HMNp(dmpe)j (M = Fe, Ru, Os Np = 2-naphthyl dmpe = Me PCH CH PMej) with HCN and terminal acetylenes give HMR(dmpe)2 that contain new M—C bonds (R = — CN, — CjR ) .

A mixture of dextro and leva crystals of the same substance may react selectively with a chiral vapour. Lin, Curtin and Paul (1974) report that crystals of the (+) and (— ) forms of 2,2-diphenyl-cyclopropane-l-carboxylic add placed on a microscope shde near a few drops of L-phenylalanine and exposed to its vapour, undergo a solid-gas reaction. The top surface of the (—) add crystal became opaque after 5 min the (-p) acid crystal was essentially unchanged. A similar experiment with D-phenylalanine showed selectivity toward the (-J-)-add crystal. 

Conjugate addition ofBuCu. 1 BuCu activated by lSi(CHj)j adds to the chiral cro-tonate 1 with excellent diastcrcosclectivity. In contrast, additions of lithium butylcupratcs arc highly dependent on the exact composition of the reagent and on the conditions, and... 

To Color a Black,—Boil half a pound of logwood chips in two quarts of water add one ounce of pear lash, and wash the work with it while hot. Then, when dry, go over the work with the following Boil half a pound of logwood in two quarts of water j add half an ounce of verdigris and green copperas, in which has been put half a pound of rusty steel or iron filings.
