摘要： A description is given of processes for the preparation of mono- and bisacylphosphines and of mono- and bisacylphosphine oxides and mono- and bisacylphosphine sulfides, which comprises first reacting organic P-monohalogenophosphines or P,P-dihalogenophosphines, or mixtures thereof, with an alkali metal or magnesium in combination with lithium, where appropriate in the presence of a catalyst, and then carrying out the reaction with acid halides and, in the case of the process for the preparation of oxides, carrying out an oxidation step and, in the case of the preparation of sulfides, reacting the phosphines so obtained with sulfur. It is characteristic, inter alia, that the processes are carried out without isolation of the intermediates.

摘要： Zpusob prípravy acylfosfinu reakcí organických halogenidu fosforu s alkalickým kovem nebo s horcíkem v kombinaci s lithiem nebo s jejich smesí, prípadne za použití katalyzátoru, za vzniku metalizovaného fosfinu, který se nechá následne reagovat s m ekvivalenty halogenidu kyselin, pricemž se zpusob provádí bez izolace meziproduktu. Takto pripravený acylfosfin se dále nechá oxidovat nebo reagovat se sírou za vzniku acylfosfinoxidu nebo acylfosfinsulfidu, pricemž se zpusob provádí bez izolace meziproduktu.

摘要： The invention relates to a process for the preparation of bisacylphosphines of formula (I), wherein n is 1 or 2, by reacting (a) organic phosphorus halides of formula (II), wherein n is 1 or 2 and Y is Br or Cl, with an alkali metal or with magnesium in combination with lithium, or with mixtures thereof, optionally in the presence of a catalyst, and (b) subsequent reaction with an acid halide of formula (III), which process is carried out without isolation of the intermediates. Also disclosed is a process for the preparation of bisacylphosphine oxides and bisacylphosphine sulfides of formula (IV), wherein n is 1 or 2 and Z is O or S, by oxidation or reaction with sulfur of bisacylphosphine of formula (I). Bisacylphosphine oxides or bisacylphosphine sulfides so obtained find application as initiators in the photopolymerisation of unsaturated compounds.
