(7) SET MPTASSEMBLY command allows you to control answer assembly formats and is set ON as a system default. To change the
MARPAT display, enter SET MPTASSEMBLY BOTH or SET MPTASSEMBLY OFF. If MPTASSEMBLY is set to BOTH or ON andassembly is not possible, only the unassembled display will be shown. For more information on SET MPTASSEMBLY see HELP T13 in
MARPAT.
(8) If you want to retain the original FQHIT/QHIT format, SET MPTASSEMBLY OFF.
(9) Even if MPTASSEMBLY is set to OFF, the unmatched G-group definitions available in the QHITEXG and FQHITEXG formats will only beshown with assembled displays. If MPTASSEMBLY is set to BOTH, an unassembled display will follow.

Displaying CAplus or MEDLINE documents for cited references
Enter the following in the DISPLAY command: L-number for the answer set; answer number (only one may be
specified); RAN.CAPLUS(x-y), RAN.MED(x-y) where (x-y) is the cited reference number, numbers, or range of
numbers; and the display format for the document to display, e.g., BIB ABS. For example, to display CAplus
records for the cited references 1 and 2 from answer 2 in the answer set L5, enter the following:=> D RAN.CAPLUS(1-2) L5 2 BIB ABS

ABSTRACT:
Arom. hydroxythiols (e.g., 3-hydroxythiophenol) are prepd. in high yield andselectivity by oxidizing an arom. aminothiol (e.g., 3-aminothiophenol) to anaminodisulfide compd., forming a bis-diazonium salt of the aminodisulfide
compd., and reacting the bis-diazonium salt with water to form an arom.
hydroxyldisulfide compd., which is then reduced to the hydroxythiol.
