Study of thermochromic behaviour of some indolinobenzospiropyrans by infrared spectroscopy
Autor: Paola Finelli, Alessandro Bertoluzza, Carlo Concilio
Publikováno v: Journal of Applied Chemistry and Biotechnology. 27:225-228
The thermochromic behaviour of some indolinobenzospiropyrans was studied by heating solid compounds in K Br. Changes in i.r. spectra are interpreted as being due to the formation of a pseudoquinonic structure, (V).

Kinetics and Mechanism of Aminolysis of Phenyl Acetates in Aqueous Solutions of Poly(ethylenimine)
Autor: Carlo Concilio, Antonio Arcelli
Publikováno v: The Journal of organic chemistry. 61(5)
Second-order rate constants (k(n)) for the aminolysis of some phenyl acetates with poly(ethylenimine) (PEI) were obtained in a pH range 4.36-11.20 at 25 degrees C in 1 M KCl. Linear Bronsted-type plots (log k(n) vs pK(N) of PEI) were found for less r

Halogen—metal interconversion in 2,7-dibromonaphthalene and 2,7-dibromoanthracene
Autor: Carlo Concilio, Gianni Porzi
Publikováno v: Journal of Organometallic Chemistry. 128:95-98
The halogen—metal exchange between 2,7-dibromonaphthalene or 2,7-dibromoanthracene and n-C 4 H 9 Li has been investigated. For exchange of only one bromine atom the best yields are achieved in diethyl ether at 20° C, while the exchange of both bro

A facile synthesis of symmetrical secondary amines from primary amines promoted by the homogeneous catalyst RuCl2(Ph3P)3
Autor: Carlo Concilio, Gianni Porzi, Bui-The-Khai
Publikováno v: Journal of Organometallic Chemistry. 208:249-251
Primary amines bearing an α-hydrogen atom are quantitatively converted to symmetrical secondary amines by heating at 185°C for 5 h in the presence of a catalytic amount of RuCl 2 (Ph 3 ) 3 .

Polyelectrolyte effects exerted by poly(ethyleneimine) on the ionization constant of substituted phenols
Autor: Carlo Concilio, Antonio Arcelli
Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :887
The ionization constants of sixteen substituted phenols, some of which have a second protogenic group (CO2H, SO3H) on the aromatic ring, have been determined spectrophotometrically at 25°C in water in the presence of poly (ethyleneimine)(PEI). The m

Effect of poly(diallyldimethylammonium chloride) and of poly(ethyleneimine) on the esterolysis of 8-acetoxyquinoline
Autor: Carlo Concilio, Antonio Arcelli
Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :1327
The esterolysis of 8-acetoxyquinoline (8-AQ) in aqueous solution in the presence of an excess of poly(diallyldimethylammonium chloride)(PDDA) or poly(ethyleneimine)(PEI) was investigated at 30°C. In the presence of PDDA hydrolysis takes place and th
