1,4-diaryl-2,3-difluoro-2-butene insecticidal and acaricidal agents

There are provided novel anthranilonitrile derivatives and related compounds which are useful for promoting growth, improving feed efficiency and for increasing the lean meat to fat ratio of warm-blooded animals.

Anthranilonitrile derivatives as useful agents for promoting growth,

There are provided novel 5-fluorobenzonitrile derivatives which exhibit low .beta..sub.1 heart stimulant activity and are useful for increasing the lean meat to fat ratio and/or enhancing the growth rate of warm-blooded animals by, orally or parenterally, administering to said animals an amount of a 5-fluorobenzonitrile derivative or a pharmacologically acceptable salt thereof effective for achieving one or more of the above-identified metabolic improvements in said warm-blooded animals.

5-fluorobenzonitrile derivatives for increasing the lean meat to fat

A method for the preparation of 1-(4'-amino-3',5'-dichlorophenyl)-2-alkyl)or dialkyl)aminoethanols. The method involves preparation of the above compounds from the corresponding aminoketones by reduction with hydrogen in the presence of platinum oxide catalyst and a promoter, such as stannous chloride.

Method for the preparation of

There is provided a process for the preparation of an amido or an ureido derivative of certain 4,5,6,7-tetrahydro-7-oxobenzo[b]thiophenes or certain 1,2,3,4-tetrahydro-4-oxonaphthalenes which can be employed as an animal growth regulant. The process comprises: oxidizing in the presence of a cobalt catalyst a compound having the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each a substituent selected from the group consisting of alkanoyl C.sub.1 -C.sub.7, halogen-substituted alkanoyl C.sub.1 -C.sub.7, carboalkoxy C.sub.1 -C.sub.4, ##STR2## and ##STR3## R.sub.3 is selected from the group consisting of hydrogen and alkyl C.sub.1 -C.sub.4 ; R.sub.4 is selected from the group consisting of hydr ogen, alkyl C.sub.1 -C.sub.8, alkanoyl C.sub.2 -C.sub.4, halogen-substituted alkanoyl (C.sub.2 -C.sub.4), and ##STR4## and when the ##STR5## moiety is cyclized each represents a moiety selected from the group consisting of succinimido, maleimido and phthalimido; X and Y are each a radical selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, nitro, alkyl C.sub.1 -C.sub.4 ; the racemic mixtures and the optical isomers thereof.

Process for preparing 4,5,6,7-tetrahydro-7-oxobenzo[b]thiophenes and

There are provided certain substituted-1,2,3,4-tetrahydro-4-imino-1-naphthylureas, methods of preparation thereof, and methods of use of said naphthylureas for enhancing feed efficiency and for promoting the growth rate of veterinary homothermic animals.
