| titleOfInvention | Preparation of trineophyltin halides |
| abstract | 1. IN A METHOD FOR PREPARING TRINEOPHYLTIN HALIDES, (PHENYL-C(-CH3)2-CH2)3-SN-X IN HIGH YIELD AND PURITY, SAID METHOD CONSISTING OF THE FOLLOWING STEPS: (1) ADDING A HYDROCARBON SOLUTION OF A STANNIC HALIDE SNX4 TO AN ETHER SOLUTION OF A NEOPHYL MAGNESIUM HALIDE PHENYL-C(-CH3)2-CH2-MG-X (2) HYDROLYZING THE RESULATANT REACTION MIXTURE USING AN AQUEOUS SOLUTION OF AN ACID HX, AND (3) CONCENTRATING THE ORGANIC PORTION OF THE RESULTANT TWO-PHASE LIQUID TO ISOLATE THE TRINEOPHYLTIN HALIDE, WHEREIN X REPRESENTS CHLORINE OR BROMINE, THE IMPROVEMENT OF WHICH CONSISTS OF MAINTAINING THE TEMPERATURE OF THE REACTION MIXTURE AT BETWEEN 55 AND 65* C. DURING THE ADDITATION OF SAID STANNIC HALIDE AND UNTIL THE TIME AT WHICH THE REACTION BETWEEN THE STANNIC HALIDE AND NEOPHYL MAGNESIUM HALIDE IS SUBSTANTIALLY COMPLETE. |
