Summary
-
1.
The synthesis of triisopropenylantimony from isopropenyl lithium and antimony trichloride, and its conversion by halogens into (CH2=C-CH3)2SbX2 are described.
-
2.
Pentaisopropenylantimony has been obtained by the reaction of triisopropenylantimony dibromide with isopropenyl lithium; with bromine it gives tetraisopropenylstibonium bromide.
-
3.
Pentavinylantimony has been synthesized by the reaction of trivinylantimony dibromide with vinylmagnesium bromide. An equivalent quantity of bromine converts it into tetravinylstibonium bromide.
-
4.
The reaction between trivinyl- and triisopropenylantimony and thallium trichloride led to trivinyl- and triisopropenyl-antimony dichloride respectively. Thallium separated as its monochloride.
