Abstract
Process for the preparation of asymmetrical alkaline earth metal organoborates and organoaluminates represented by the formula I: ##STR1## and asymmetrical alkaline earth metal organoarsenates and organophosphates represented by the formula II: ##STR2## wherein Z is selected from the group consisting of boron and aluminum; X is selected from the group consisting of phosphorus and arsenic; M is an alkaline earth metal; and in which R.sub.1 -R.sub.6 are independently selected from alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, and cyano with the proviso that R.sub.1 -R.sub.6 are not all the same.
Claims6
A process for preparing an asymmetrical alkaline earth metal organoborate or aluminate of the formula:
- ##STR5## wherein Z is selected from the group consisting of boron and aluminum, M is an alkaline earth metal, and R.sub.1 -R.sub.4 are independently selected from alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, and cyano by the steps of:
- (1) reacting an organohaloboron or organohaloaluminum of the formula:
- Z(R).sub.2 W
- with
- (2) an organoalkaline earth metal compound of the formula:
- M(R').sub.2
- wherein Z is as defined above, R and R' are as defined above for R.sub.1 -R.sub.4 with the proviso that R and R' are not the same, and W is halogen.
A process for preparing an asymmetrical alkaline earth metal organoarsenate or organophosphate of the formula:
- ##STR6## wherein X is selected from the group consisting of arsenic and phosphorus, M is an alkaline earth metal, and R.sub.1 -R.sub.6 are independently selected from alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, and cyano by the steps of:
- (1) reacting an organohaloarsorane or organohalophosphorane of the formula:
- X(R).sub.4 W
- with
- (2) an organoalkaline earth metal compound of the formula:
- M(R').sub.2
- wherein X and R are as defined above, R and R' are as defined above for R.sub.1 -R.sub.6 with the proviso that R and R' are not the same, and wherein W is halogen.
