Dendrimer-Phosphine Complexes with Platinum(0) at the Core: Dendrimer-Phosphine Complexes with Platinum(0) at the Core. Balaji, B. S.; Obora, Yasushi; Ohara, Daisuke; Koide, Shigehiro; Tsuji, Yasushi (Catalysis Research Center and Division of Chemistry Graduate School of Science, Hokkaido University, Sapporo 060-0811, Japan). Organometallics, 20(25), 5342-5350 (English) 2001 American Chemical Society. CODEN: ORGND7. ISSN: 0276-7333. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 35, 78 Prepn. of novel mono- and bidentate phosphine ligands having dendrimer moiety is reported. Monodentate (1a-c) (shown as I; R = G1 (1a), R = G2 (1b), R = G3 (1c)) and bidentate ligands (5a,c) (shown as II; R = G1 (5a), R = G2 (5b)) were synthesized from bis(4-hydroxyphenyl)phenylphosphine oxide (3) and 1,2-bis(dichlorophosphino)ethane, resp., in high yields. The defect-free monodisperse nature of these compds. was confirmed by 31P NMR and elemental anal. as well as by ESI mass spectra. Complexation of these ligands with PtCl2(COD) followed by NaBH4 redn. in a THF/H2O mixt. gave Pt(0) complexes PtL3 10a,b (having 1a,b as monodentate ligands (L)) and Pt(L-L)2 (13a,b) (5a,b as bidentate ligands (L-L)), resp. Preliminary studies on oxidative addn. of RI (R = CH3 or C6H5) to 10a,b showed that the metal center is easily accessible. Further, mol. modeling of 13b showed nanoscale flattened globular structure of the complex with an approx. diam. of 4.4 nm.

Polyamide substituted with aldehyde and isonitrile residues: Polyamide substituted with aldehyde and isonitrile residues. Sokolovsky, Mordechai; Freeman, Amihay; Goldstein, Leon (Israel ). Israeli IL 42516 30 Nov 1976,20 pp. (English). (Israel). CODEN: ISXXAQ. CLASS: IC: C08G020-38. APPLICATION: IL 19730614. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Section cross-reference(s): 7 Polyamides with active side groups, useful, e.g., for the attachment and immobilization of enzymes, are prepd. Thus, nylon 6 [25038-54-4] powder was suspended in 3N HCl at 20.degree. for various lengths of time to obtain a desired degree of hydrolysis. Partially hydrolyzed nylon 6 powder (2 g) suspended in 80 mL iso-PrOH was reacted with 20 mL MeCHO [75-07-0] and 8 mL 1,6-diisocyanohexane [929-57-7] at room temp. for 24 h. The resulting polyisonitrile nylon (50 mg) was suspended in 2 mL cold soln. (0.1 molar phosphate and 0.5 molar NaOAc) and 6 mg trypsin [9002-07-7] was added, followed by 0.1 mL MeCHO, and the mixt. stirred overnight at 4.degree., after which the insol. enzyme deriv. was filtered off; its enzymic activity was 35%. Similarly polyisonitrile nylon was attached to pepsin [9001-75-6]. 4,4'-Diaminodiphenylmethane [101-77-9] nylon was also prepd. and papain [9001-73-4] and p-bromophenol [106-41-2] attached to it.
