 - Please ensure that no labels from a journals publication are included (e.g. information such as compound No **233c** should be removed)
 - Chemical names are not capitalized unless they are the first word of a sentence or are part of a title or heading. Then, the first letter of the syllabic portion is capitalized, not the locant, stereoisomer descriptor, or positional prefix.
 - Note and emphasize any hazards, such as explosive or pyrophoric tendencies and toxicity, in a separate paragraph introduced by the heading “Caution:”. Include precautionary handling procedures, special waste disposal procedures, and any other safety considerations in adequate detail so that workers repeating the experiments can take appropriate safety measures.
-- Please ensure that no abbreviations are used that need further explanations. A list of common abbreviations are given in the section "abbreviations" of this documentation. If you need to add abbreviations, please define them in "additional information for publication and purification". For common abbreviations, please see section ["Abbreviations"](abbreviations)

 - The description of the reaction should end with a sentence that includes the name of the isolated/gained compound and its amount in mg/g, mmol/mol and %. E.g. "After purification, 1-naphthyl-{1-[4-(trifluoromethyl)benzyl]indol-3-yl}methanone (62.3 mg, 145 μmol) was obtained in 27% yield as a colorless solid". The name can be omitted and replaced by "the target compound" or "the product" if the name can only be hardly accessed or is very long.
 - Avoid using trademarks and brand names of equipment and reagents. Use generic names; include the trademark in parentheses after the generic name only if the material or product used is somehow different from others. Remember that trademarks often are recognized and available as such only in the country of origin.
