Polyisobutenylphenol-containing Mannich adducts are prepared bya) alkylation of a phenol with highly reactive polyisobutene having a number average molecular weight of less than 1000 and a polydispersity of less than 3.0 at below about 50° C. in the presence of an alkylation catalyst;b) reaction of the reaction product from a) withb1) an aldehyde chosen from formaldehyde an oligomer and a polymer of formaldehyde andb2) at least one amine which has at least one primary or one secondary amino...

The invention relates to crystalline hydrates of substituted nicotinic acid anilide derivatives and substituted benzoic acid anilide derivatives of formula (1) the production and use thereof to combat phytopathogenic fungi and undesirable insect and accaride attacks and/or to regulate the growth of plants; wherein A represents (A1) or (A2) R1 represents phenyl substituted by halogen R2 represents difluoromethyl trifluorormethyl chlorine bromine or iodine and R3 represents trifluoromethyl or chlo...

The invention relates to a method for producing Mannich adducts that contain polyisobutylene phenol by: a) alkylating a phenol with highly-reactive polyisobutylene at a temperature lower than approximately 50 DEG C and in the presence of an alkylation catalyst; b) reacting the reaction product from a) with formaldehyde an oligomer or with a polymer of the formaldehyde and with at least one amine of formula HNR4R5 where R4 and R5 are selected from C1- to C20-alkyl radicals; or c) reacting the rea...

A process for the racemisation of enantiomerically enriched 1-benzyl-4-(4- fluorophenyl)-3-hydroxymethyl-1236-tetrahydropyridine which is a useful intermediate in the preparation of paroxetine. Formula (A) means that the compound (I) has an enantiomeric excess of one enantiomer over the other enantiomer. R1 and R2 are defined as in claim 1.

The invention relates to a process for preparing optically active alkylsuccinic acid monoalkyl esters of the formula (I)where D and E are independently of one another H C1-C10 alkyl R is C1-C10 alkyl aryl or alkylaryl.
