Sommelet reaction for oxidation of benzylic halides to aldehydes.[23] It has also found use in the preparation of isothiocyanates from dithiocarbamates.[24] Because of its toxicity it has largely fallen out of favour, but it still finds occasional use, for example as a bromide scavenger during SN1 substitution.[25]සුරක්ෂිතභාවය[සංස්කරණය]ප්‍රධාන ලිපිය: Lead poisoningLead(II) nitrate is toxic, and ingestion may lead to acute lead poisoning, as is applicable for all soluble lead compounds.[26] All inorganic lead compounds are classified by the International Agency for Research on Cancer (IARC) as probably carcinogenic to humans (Category 2A).[27] They have been linked to renal cancer and glioma in experimental animals and to renal cancer, brain cancer and lung cancer in humans, although studies of workers exposed to lead are often complicated by concurrent exposure to arsenic.[28] Lead is known to substitute for zinc in a number of enzymes, including δ-aminolevulinic acid dehydratase (
