Millimeter wave spectra of ethyl isocyanate and searches for it in Orion KL and Sgr B2.
Kolesniková L, Alonso ER, Tercero B, Cernicharo J, Alonso JL. Kolesniková L, et al. Astron Astrophys. 2018 Aug;616:A173. doi: 10.1051/0004-6361/201833223. Epub 2018 Sep 7. Astron Astrophys. 2018. PMID: 30369619 Free PMC article.
CONTEXT: Relatively high abundances of methyl isocyanate (CH(3)NCO), a methyl derivative of isocyanic acid (HNCO), found in the Orion KL and Sgr B2 molecular clouds suggest that its ethyl derivative, ethyl isocyanate (CH(3)CH(2)NCO), may also be presen …

Investigation of diethylthiourea and ethyl isothiocyanate as potent skin allergens in chloroprene rubber.
Ramzy AG, Hagvall L, Pei MN, Samuelsson K, Nilsson U. Ramzy AG, et al. Contact Dermatitis. 2015 Mar;72(3):139-46. doi: 10.1111/cod.12318. Epub 2014 Dec 23. Contact Dermatitis. 2015. PMID: 25532938
RESULTS: DETU was identified at concentrations of 2.7-9.4 g/cm(2) in all samples, whereas neither DBTU nor DPTU was detected. At 37C, degradation of DETU in the materials to ethyl isothiocyanate (EITC) was detected. EITC and ethyl isocyanate showed extreme an …

Gallium "Shears" for C=N and C=O Bonds of Isocyanates.
Dodonov VA, Chen W, Zhao Y, Skatova AA, Roesky PW, Wu B, Yang XJ, Fedushkin IL. Dodonov VA, et al. Chemistry. 2019 Jun 21;25(35):8259-8267. doi: 10.1002/chem.201900517. Epub 2019 May 13. Chemistry. 2019. PMID: 30892746
The reactions with both isocyanates result in new C-C and N-Ga single bonds. In the case of allyl isocyanate, the [2+4] cycloaddition across one C=C-N-Ga fragment of 1 is accompanied by insertion of a second allyl isocyanate molecule into the Ga-N bond of the same f …
