Abstract: A group of novel, low temperature liquid crystalline compounds with terminal, primary or secondary amino polar electron donating groups are disclosed. These include, for example, p-alkyl-or alkoxy-phenylcyclohexanes, bicyclohexyls or biphenyl ring systems, substituted at the p' position with alkyl primary or secondary amines, of which one example is p-(4-trans-n-pentylcyclohexyl)benzylamine.

Abstract: Aminomethylation of olefins which employs a homogeneous catalyst which is a solution in a suitable solvent of mixed ruthenium and iron carbonyls. The overall reaction may be represented as follows: ##STR1## where R.sub.1 and R.sub.2 are hydrogen or essentially hydrocarbon groups. The reaction proceeds by way of an aldehyde intermediate. Accordingly, the starting material may be an aldehyde instead of an olefin.

Abstract: Compounds are disclosed of general formula (I) ##STR1## in which R.sub.1 represents a hydrogen atom, a halogen atom or a group OR.sub.2, in which R.sub.2 represents a hydrogen atom, an alkyl group or an acyl group, R.sub.3 represents hydrogen or an alkyl, alkenyl or aryl group, R.sub.4 and R.sub.5 which may be the same or different, each represents a hydrogen atom or an alkyl, alkenyl or alkynyl group optionally substituted by an aryl or cycloalkyl group;or R.sub.4 and R.sub.5 together with the nitrogen atom may form a saturated four to seven membered ring,with the provisos that, when R.sub.4 and R.sub.5 simultaneously represent hydrogen atoms then (i) when R.sub.1 is hydrogen then R.sub.3 is not methyl and (ii) the compounds are the .beta.-isomers;and their physiologically acceptable salts.Compounds of formula (I) may be prepared from the corresponding .alpha.- or .beta.-configuration alcohols, from an aziridine intermediate or by a variety of alkylation procedures whereby the group R.sub.4 and/or R.sub.
