Iron Aminocarbene Complexes Containing a Double C:C Bond in the N-Substituent: Preparation and Reactivity.

CODEN: ORGND7. ISSN: 0276-7333. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Reaction of N,N-diallylbenzamide with Na2Fe(CO)4 and Me3SiCl afforded chelated cis-tricarbonyl[(h2-N-allyl-N-allylamino)(phenyl)carbene]iron(0) directly. The same reaction of N-(3-buten-1-yl)-N-methylbenzamide proceeded with migration of the double bond to the allylic position, giving a mixt. of chelated cis-tricarbonyl[(h2-N-(2-butenyl)-N-methylamino)(phenyl)carbene]iron(0) and nonchelated tetracarbonyl[(N-(2-butenyl)-N-methylamino)(phenyl)carbene]iron(0). N-(3-Buten-2,2-dimethyl-1-yl)-N-methylbenzamide, in which migration of double bond is not possible, gave a mixt. of E and Z isomers of nonchelated tetracarbonyl[(N-(2,2-dimethyl-3-butenyl)-N-methylamino)(phenyl)carben e]iron(0). Thermolysis of the latter furnished 1-methyl-3,3-dimethyl-6-phenyl-1,2,3,4-tetrahydropyridine as the only product.

Liquid crystalline polymer gels: preparation and swelling behavior of cellulose-based networks. Marsano, E.; Bianchi, E.; Boero, E.; Gastaldi, G.; Focher, B.

DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Cellulose (I) organo gels with liq. cryst.In this article, certain chemicals are used. Some of their cas registry numbers are 39716-58-0 and 111-50-2 (LC) order were prepd. by crosslinking I chains with a difunctional unit, adipoyl chloride, or a monofunctional mol. contg. a reactive double bond, 4-pentenoyl chloride. Both gels displayed a reversible change from LC order to isotropic phase by changing the amt. of solvent. The relation between the crit. concn. at which the LC phase was stable and the degree of crosslinking depended on the crosslinking agent. Both gels swelled in dimethylacetamide (II) and acetone (III), but the degree of swelling decreased with the degree of crosslinking in II, whereas an increase was obsd. in III. This behavior was explained by taking into account the different compns. of the networks. .
