Abstract: A NEW CLASS OF DIAMIDODIALANES, REPRESENTD BY THE FORMULA:

X2-AL-N(-R)-(CH2)N-N(-R)-AL-X2

WHEREIN X IS HYDROGEN, HALOGEN OR A SECONDARY AMINE RADICAL; EACH R IS A HYDROCARBON RADICAL AND SAID R''S, TOGETHER, ARE MEMBERS OF THE GROUP CONSISTING OF (A) A PAIR OF HYDROCARBON RADICALS THAT ARE UNLINKED DIRECTLY TO EACH OTHER, AND (B) A PAIR OF HYDROCARBONS THAT ARE LINKED DIRECTLY TO EACH OTHER TO FORM A RING; AND N IS A WHOLE NUMBER RANGING FROM 2 TO 6. THE RESEPECTIVE MEMBERS ARE USEFUL AS A COMPONENT OF A CATALYST SYSTEM IN THE POLYMERIZATION OF OLEFINS, DIOLEFINS AND POLYENES, AND MAY BE PREPARED BY A SUBSTITUTION REACTION OF A DIAMINE CHLOROHYDRATE WITH AN ALUMINUM HYDRIDE.
