    Abstract: Process for the preparation of organophosphorus derivatives of 2,4-di-t-butylphenol having a high content of organophosphorus derivatives of biphenyl, characterised in that, in the first step, a 4,4'-dihalobiphenyl whose halogen has an atomic weight of at least 35 is reacted under Grignard conditions with magnesium to give the corresponding Grignard compound, which is further reacted, in a second step, with bis(2,4-di-t-butylphenyl) chlorophosphite of the formula IV … … to form a mixture in which at least 50% by weight of the phosphorus is bound in the form of tetrakis(2,4-di-t-butylphenyl)-4,4'-biphenylene diphosphonite of the formula I … … the bonding of the phosphorus being determined by P-NMR analysis. … The invention furthermore relates to a polyolefin moulding composition which contains tetrakis(2,4-di-t-butylphenyl)- 4,4'-biphenylene diphosphonite of the formula I prepared by reacting a 4,4'-dihalobiphenyl whose halogen has an atomic weight of at least 35, with magnesium to give the Grignard compound and subsequent reaction thereof with bis(2,4-di-t-butylphenyl) chlorophosphite. … The moulding composition has improved properties compared with moulding compositions which contain said phosphonite prepared in accordance with the prior art. … The invention also relates to a process for the preparation of 4,4'-dihalomagnesium compounds of biphenyl by reacting a 4,4'-dihalobiphenyl whose halogen has an atomic weight of at least 35 with magnesium in the absence of an entrainer, in which process a 4,4'-dihalobiphenyl whose halogen has an atomic weight of at least 35 is reacted with finely divided magnesium kept in suspension.

    Abstract: Novel 6-aryl-6H-dibenzo¢c,e!¢1,2!oxaphosphorines, a process for their preparation, and their use for stabilizing plastics, in particular polyolefin molding compositions A process for the preparation of a dibenzo¢c,e!¢1,2!oxaphosphorine of the formula I (I) where n = 1 or 2 and in which R1, as a monovalent radical, is a phenyl radical, which may carry 1 to 3 substituents, or a naphthyl radical, which may carry 1 to 5 substituents, the substituents being identical or different nonaromatic hydrocarbon, alkoxy, alkylthio or dialkylamino radicals, in each case having 1 to 8 carbon atoms, aryl or aryloxy, in each case having 6 to 10 carbon atoms, or halogen having an atomic number of from 9 to 35, or, as a divalent radical, is a phenylene or biphenylene radical which is unsubstituted or substituted by up to 4 nonaromatic hydrocarbon radicals having 1 to 8 carbon atoms, or is a naphthylene radical which is unsubstituted or carries 1 to 4 nonaromatic hydrocarbon radicals having 1 to 8 carbon atoms as substituents, which comprises, in a first step, reacting a hydrocarbon halide R1-(Hal)n in which R1 is as defined above, n = 1 or 2, and the halogen has an atomic weight of at least 35, under Grignard conditions with an at least stoichiometric amount of magnesium to give the corresponding Grignard compounds R1(MgHal)n, and reacting the latter, in a second step, with 6-chloro-6H-dibenzo¢c,e!¢1,2!oxaphosphorine, forming the compounds of the formula I. The invention furthermore relates to a plastic molding composition, in particular a polyolefin molding composition, which contains compounds of the formula I. The molding composition has improved properties compared with molding compositions containing oxaphosphorines prepared in accordance with the prior art.
