Summary
-
1.
On the basis of chemical and spectrographic data it was shown that the product of the action of sodium diethyl phosphite on 2-chlorocyclopentanone is diethyl 1,2-epoxycyclopentylphosphonate. The product of the action of sodium diethyl phosphite on 2 -bromocyelohexanone is a mixture of 1-cyclohexen-1-yl diethyl phosphate and diethyl 1,2-epoxycyclohexylphosphonate.
-
2.
The products of the action of sodium diethyl phosphite and of triethyl phosphite on 2-chloro-2-methyl-cyclohexanone consist of diethyl 2-methyl-1-cyclohexen-1-yl phosphate; the product of the action of triethyl phosphite on 3-bromo-3-methyl-2-butanone is diethyl isopropenyl phosphate.
-
3.
The product of the action of sodium diethyl phosphite on 3-bromocamphor is the corresponding mixed phosphoric ester.
