Negative-ion fast atom bombardment mass spectrometry is quite useful for the identification of products and by-products formed during the synthesis of nucleoside 3′-phosphoramidites. The data shown that detritylation and oxidation are side reactions which occur during the synthesis of monomeric units used in the construction of oligodeoxyribonucleotides by the phosphite triester method. © 1986.
