N, N-Dialkyl 2-oximinoacetoacetamides also were found to give pyrroles when reacted under Knorr conditions with 3-substituted-2, 4-pentanediones, in yields comparable to the corresponding esters ( around 45 % ).

"' Propylisopropyltryptamine "'( "'PiPT "') is a chemical in the tryptamine family, which produces hallucinogenic effects that resemble those of other related dialkyl tryptamine derivatives, although PiPT is reportedly relatively weak and short lasting.

Reduction of CpCo ( CO ) 2 with sodium yields the dinuclear radical [ Cp 2 Co 2 ( CO ) 2 ] ", which reacts with alkyl halides to give the dialkyl complexes [ Cp 2 Co 2 ( CO ) 2 R 2 ].

A German patent claimed that the reaction of 1, 3, 2, 4-dithiadiphosphetane 2, 4-disulfides with dialkyl cyanamides formed plant protection agents which contained six-membered ( P-N = C-N = C-S-) rings.

The analog compound with the " N ", " N "-dialkyl substituents constrained into a pyrrolidine ring, is a slightly stronger agonist for the 5-HT 1A receptor and retains the selectivity over the 5-HT 2A / 2C receptors.

It was claimed in a German patent that the reaction of 1, 3, 2, 4-dithiadiphosphetane 2, 4-disulfides with dialkyl cyanamides formed plant protection agents which contained six-membered ( P-N = C-N = C-S-) rings.

The report contains discussion of various harmful chemicals " likely to be present " in the waste sodium hydroxide, cobalt phthalocyanine sulfonate, coker naphtha, thiols, sodium alkanethiolate, sodium hydrosulfide, sodium sulfide, dialkyl disulfides, hydrogen sulfide and notes that some of these " may cause harm at some distance ".

Another study found that each 10-fold increase in urinary concentration of organophosphate metabolites was associated with a 55 % to 72 % increase in the odds of children being diagnosed with ADHD . Researchers analyzed the levels of organophosphate residues in the urine of more than 1, 100 children aged 8 to 15 years old, and found that those with the highest levels of dialkyl phosphates, which are the breakdown products of organophosphate pesticides, also had the highest incidence of ADHD . Overall, they found a 35 % increase in the odds of developing ADHD with every 10-fold increase in urinary concentration of the pesticide residues.
