1,5-Pentanediol as a matrix for negative-ion fast-atom-bombardment mass spectrometry: 1,5-Pentanediol as a matrix for negative-ion fast-atom-bombardment mass spectrometry. Takayama, Mitsuo (Fac. Pharm. Sci., Toho Univ., Funabashi 274, Japan).There are some reagents with their cas registry numbers 10236-47-2 and 153-18-4 are used in this study. Org. Mass Spectrom., 26(12), 1123-4 (English) 1991. CODEN: ORMSBG. ISSN: 0030-493X. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Neg.-ion fast-atom-bombardment mass spectra of rutin and naringin with liq. matrixes, e.g. 1,5-pentanediol, is described. .

Ruthenium complex catalyzed N-heterocyclization: Ruthenium complex catalyzed N-heterocyclization. Syntheses of N-substituted piperidines, morpholines, and piperazines from amines and 1,5-diols. Tsuji, Yasushi; Huh, Keun Tae; Ohsugi, Yukihiro; Watanabe, Yoshihisa (Fac. Eng., Kyoto Univ., Kyoto 606, Japan). J. Org. Chem., 50(9), 1365-70 (English) 1985. CODEN: JOCEAH. ISSN: 0022-3263. 101-02-0 which is the cas registry number is also used here. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 27 1,5-Pentanediol reacts with aliph. and arom. primary amines in the presence of a Ru catalyst modified with phosphine ligands to give N-substituted piperidines in fair to goods yields. The reactions were carried out at 150-180° for 5 h in dioxane.In this study，101-02-0 is also used. The nature of the phosphorus ligands has a remarkable effect on the catalytic activity. For the reaction of arom. amines, Ph3P is effective, while for aliph. amines more basic Bu3P or Et3P is preferable. Amines also react with diethylene glycol and N-substituted diethanolamines in the presence of the Ru catalyst to give N-substituted morpholines and piperazines in good yields, resp. ..
