Two aspects of penta-coordination in organometallic chemistry
Penta-coordination is shown to be the basic concept underlying the physical and chemical properties of organotin compounds. The principles are outlined and applied to the synthesis, and to the static and dynamic stereochemistry of these compounds; they are now being extended to chromium complexes. © 1972, Walter de Gruyter.

Influence de la structure moléculaire sur la fréquence et l'intensité intégrée de la vibration νCN d'une serie de nitriles polycycliques aromatiques en spectroscopie infra-rouge-I. Théorie électronique de l'intensité intégrée. Mise en évidence d'un effet stérique à la solvatation
This work describes an electronic theory, based on L.C.A.O. of the integrated intensities of localized vibrators in π-electron systems. Using this theory, we have shown that the solvation of polycyclic aromatic nitriles (CCl4) is partially inhibited by steric effects due to peri hydrogen atoms. © 1964.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
6-nitro-2,3-dipiperidinoquinoxaline: Its unexpected formation from 2-chloro-7-nitroquinozaline.
Excess piperidine and 2-chloro-7-nitroquinoxaline 1 in diethyl ether give large amounts of the unexpected disubstitution product 6-nitro-2,3-di-piperidinoquinoxaline 3. The mechanism of this very unusual nucleophilic substitution of hydrogen is suggested to involve the oxidation of the dipiperidino-dihydroquinoxaline 10 by dissolved oxygen. © 1991.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
