<P>In the typical procedure given for the reaction of diazomethane with trinitromethane,
the sentence ‘Then the mixture was concentrated to give 1.30 g of a yellow oil consisting
of
1 and
2 in the ratio 7:3 (as shown by
1H NMR)’ should instead read ‘The described synthesis was run four times and the combined
reaction mixtures were concentrated to give 1.30 g of a yellow oil consisting of
1 and
2 in the ratio of 7:3 (as shown by
1H NMR)’.</P><P></P><P>The authors apologize for this omission.</P>
