    摘要: A process for the preparation of organophosphorus derivatives of 2,4-di-tert-butylphenol with a high proportion of organophosphorus derivatives of biphenyl, which comprises reacting, in a first step, a 4,4'-dihalobiphenyl whose halogen has an atomic weight of at least 35, under Grignard conditions with magnesium to form the corresponding Grignard compound and this is further reacted in a second step with bis(2,4-di-tert-butylphenyl) chlorophosphite with the formation of a mixture in which at least 50% by weight of the phosphorus is combined in the form of tetrakis(2,4-di-tert-butylphenyl) 4,4'-biphenylenediphosphonite. The invention further relates to a polyolefin molding composition containing tetrakis(2,4-di-tert-butylphenyl) 4,4'-biphenylenediphosphonite which was prepared by reaction of a 4,4'-dihalobiphenyl whose halogen has an atomic weight of at least 35 with magnesium to form the Grignard compound and by subsequent reaction with bis(2,4-di-tert-butylphenyl) chlorophosphite. The invention furthermore 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 in the absence of an entrainer, with fine-particle magnesium which is held in suspension.
