    • A process for the preparation of alkyl arylphosphinites of the formula (I) ##STR1## in which R.sup.1 is (C.sub.1 -C.sub.16)-alkyl, cyclohexyl, cyclopentyl, aryl which can also be substituted by halogen, (C.sub.1 -C.sub.6)-alkoxy groups R.sup.2 is aryl which can also be substituted by halogen, (C.sub.1 -C.sub.6)-alkyl, (C.sub.1 -C.sub.6)-alkoxy groups, where R.sup.1 and R.sup.2 together with the phosphorous atom can also form a ring and R.sup.3 is (C.sub.1 -C.sub.4)-alkyl, which comprises reacting halo(aryl) phosphines of the formula (II) ##STR2## in which R.sup.1, R.sup.2 have the meaning given above and X is halogen, with ammonia-containing alcohols of the formula (III) R.sup.3 OH (III) in which R.sup.3 has the meaning given above.
