Abstract: A method of treating a surface of at least one part by individual sources of an electron cyclotron resonance plasma is characterized by subjecting the part(s) to at least one movement of revolution with regard to at least one fixed linear row of elementary sources. The linear row or rows of elementary sources are disposed parallel to the axis or axes of revolution of the part or parts.

Abstract: A process for preparing a 2-alkoxy-6-(trifluoromethyl)pyrimidine-4-ol of the formula I: wherein R is C1-C8 alkyl. First a cyanogen halide, that is, cyanogen chloride ClCN or cyanogen bromide BrCN, is reacted with a C1-C8 alcohol ROH and/or a C1-C8 alcoholate in the presence of a base to give the corresponding symmetric imidocarbonic acid dialkylester of the formula II: In a second step, the imidocarbonic acid diakylester is reacted with trifluoromethyl acetoacetic acid ethyl ester in the presence of ammonia to yield the compound of formula I.

Abstract: A process for the preparation of dihydroxypyrimidine derivatives of the general formula: in which R1 and R2 are identical or different and are a hydrogen atom, aryl group, or a C1-C4-alkyl group or an aryl group, starting from a compound of the general formula: in which R2 has the meaning mentioned above and R3 is —CN or COOR4, in which R4 is a C1-C4-alkyl group.

Abstract: A process for preparing substituted pyrimidine derivatives of the general formula (I): in which a [3-(dimethylamino)-2-azaprop-2-en-1-ylidine]dimethylammonium halide is reacted with a substituted acetamide. The compounds of general formula (I) are important intermediate products for pharmaceutical or agrochemical active substances.

Abstract: This invention relates to use of oligonucleotides having at least one nucleotide that is substituted at the 4'-position of the sugar moiety with a substituent other than hydrogen as nucleotide probes in methods for detecting the presence or amount of a polynucleotide analyte in a sample suspected of containing the polynucleotide analyte. These oligonucleotides can also be packaged in diagnostic assay kits.

Abstract: A novel process for the preparation of a 2-alkoxy-6-(trifluoromethyl)pyrimidin-4-ol of the general formula: ##STR1## in which R is a C.sub.1 -C.sub.8 -alkyl group. In the process, cyanamide is reacted with the appropriate alcohol in the presence of hydrogen chloride to give the corresponding alkoxyisourea hydrochloride, which is then converted with ethyl trifluoroacetoacetate in the presence of an alkali metal hydroxide, which is in water, to the end product of the formula I.

Abstract: This invention relates to oligonucleotides having at least one nucleotide that is substituted at the 4' position of the sugar moiety with a substituent other than hydrogen. These oligonucleotides are useful in hybridization assays and as therapeutic agents.
