A 1:1:2 mixed orthocarbonate of the formula ##STR1## wherein R and R" are each one of the following groups --CH.sub.2 C(NO.sub.2).sub.2 CH.sub.3, --CH.sub.2 C(NO.sub.2).sub.3, --CH.sub.2 CF(NO.sub.2).sub.2, --CH.sub.2 CF.sub.2 (NO.sub.2), and --CH.sub.2 CF.sub.3, and R' is one of the following CH.sub.2 CF(NO.sub.2).sub.2, CH.sub.2 CF.sub.2 (NO.sub.2), and 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, CH.sub.2 C(NO.sub.2).sub.3, CH.sub.2 CF.sub.2 (NO.sub.2), or 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.
A 1:1:2 mixed orthocarbonate of the formula ##STR9## wherein R and R" are selected from the group consisting of
A 1:3 mixed orthocarbonate of the formula ##STR10## wherein R=R", R.noteq.R', and R'.noteq.R" and R and R" are selected from the group consisting of
A disulfide of the formula ##STR11## wherein R.noteq.R' and R is selected from the group consisting of
A process for preparing 1:1:2 mixed orthocarbonates of the formula ##STR12## comprising the following steps in order:
