Abstract
A 1:1:2 mixed orthocarbonate of the formula ##STR1## wherein R and R" are each one of the following groups PA0 --CH.sub.2 C(NO.sub.2).sub.2 CH.sub.3, PA0 --CH.sub.2 C(NO.sub.2).sub.3, PA0 --CH.sub.2 CF(NO.sub.2).sub.2, PA0 --CH.sub.2 CF.sub.2 (NO.sub.2), and PA0 --CH.sub.2 CF.sub.3, and PA0 R' is one of the following PA0 CH.sub.2 CF(NO.sub.2).sub.2, PA0 CH.sub.2 CF.sub.2 (NO.sub.2), and PA0 CH.sub.2 CF.sub.3, provided that R.noteq.R', R.noteq.R", and R'.noteq.R". These 1:1:2 orthoconates are produced by the following reaction sequence: ##STR2## wherein R, R', and R" are as defined above. By choosing R and R" to be the same and either --CH.sub.2 (NO.sub.2).sub.2 CH.sub.3 or --CH.sub.2 C(NO.sub.2).sub.3 in the above reaction, 1:3 mixed orthocarbonates of the formula ##STR3## wherein R.noteq.R', R".noteq.R', R=R", and R and R" are each CH.sub.2 C(NO.sub.2).sub.2 CH.sub.3, PA0 CH.sub.2 C(NO.sub.2).sub.3, PA0 CH.sub.2 CF.sub.2 (NO.sub.2), or PA0 CH.sub.2 CF.sub.3, and R' is CH.sub.2 CF(NO.sub.2).sub.2, CH.sub.2 CF.sub.2 (NO.sub.2) or CH.sub.2 CF.sub.3 may be prepared.
