摘要:
Novel naphthylcyclopentanone derivatives are described which are useful as intermediates for and as pharmacological agents. Representative compounds are 3-(6''-methoxy-2''-naphthyl)-2methylcyclopentanone-2-acetic acid, the cyclopentanol analog, their methyl and other alkyl esters, acid addition salts thereof, their racemic and optically active forms.

1. A PROCESS FOR THE CLEAVAGE OF A THIOKETAL COMPRISING REACTING A THIOKETAL WITH AN ALKYLATING AGENT SELECTED FROM THE GROUP CONSISTING OF LOWER ALKYL HALIDE OF 1 TO 7 CARBON ATOMS AND BENZYL HALIDE IN THE PRESENCE OF WATER TO OBTAIN THE CORRESPONDING CARBONYL DERIVATIVE.
摘要:
COMPOUNDS HAVING A 1,3-DITHIOLANE, 1,3-DITHIANE, 1,3,5OXADITHIANE OR 1,3,5-TRITHIANE SUBSTIUENT ARE CONVERTED TO ALDEHYDE OR KETONES BY TREATING WITH CERTAIN ORGANIC HALIDES OR SULFATES.
WHEREIN X=0 OR 18 AND W IS A BIFUNCTIONAL ALIPHATIC OR AROMATIC RADICAL OXYGEN, SULFUR, OXYDIALKYL, OR THIODIALKYL RADICAL; R1 AND R2 ARE EACH INDEPENDENTLY A LOWER ALKYL OR HALOALKYL RADICAL; R3, R4, R5, R6, R7, AND R8 CAN EACH INDEPENDENTLY BE HYDROGEN, A LOWER ALKYL RADICAL OR HALOGEN; AND Z IS EITHER SULFUR OR CARBON. (2) A PROCESS FOR MAKING THE NEW COMPOSITION OF MATTER DESCRIBED IN (1) ABOVE BY CONTACTING A BISPHENOL
AND FURTHER CONTACTING THE INTERMEDIATE BIS-T-BENZYL ALCOHOL WITH EITHER THIONYL CHLORIDE OR PHOSGENE IN THE PRESENCE OF A TERTIARY AMINE. (3) A PROCESS FOR CURING BY HEATING WITH THE NEW COMPOUNDS OF SECTION (1) ORGANIC POLYMERS CONTAINING "ACTIVE HYDROGEN" ATOMS, "ACTIVATED DOUBLE BONDS," OR ALLYLIC CHORINE.
摘要:
An ionic liquid composition comprising a complex of a trihalo aluminum (III) species with at least one organic uncharged ligand comprising a ring structure having at least three ring carbon atoms and at least one ring heteroatom selected from nitrogen and sulfur, wherein the complex is a liquid at a temperature of 100° C. or less. Methods of electroplating aluminum onto a metallic substrate using the above-described ionic liquid composition are also described.
摘要:
Photoactivatable prepolymers and methods of use thereof are disclosed for microencapsulation of a substantially water-insoluble material within a nonporous shell. As provided herein, the microencapsulated material is released with no more than a slow release rate. Upon exposure of the nonporous shell to light, the nonporous shell is converted into a porous shell having an increased release rate for the microencapsulated material.
