In the reaction of p-nitrophenyl isothiocyanate with AT,W-tetramehtyl-W"-n-butyl-guanidine 49 an exchange reaction with formation of n-butyl isothiocyanate 50 is observed. ... 

Secondary butyl isothiocyanate, CH3. CH. CH(CH3). N C S, has been isolated from the oils of Cardamine amara and Cochlearia. It is a liquid with a powerful, irritating sulphur odour, having a specific gravity 0 9415 and boiling at 159° to 160°. Warmed with alcoholic solution of ammonia, it yields a thiourea, melting at 135° to 136°. 

Jimenez et al. [24] have synthesized receptors l,5-bis-N-(9,10-dioxo-9,10-di-hydroanthracen-l-yl)-AT-butylthiourea 18 and its urea analogue, 1,5-bis-AT-(9,10-dioxo-9,10-dihydroanthracen-l-yl)-N/-butylurea 19,by condensation of 1,5-diaminoanthraquinone with butyl isothiocyanate and butyl isocyanate, respectively. 

The use of N-methyl-N -t-butylcarbodiimide as a diagnostic tool results in the formation of t-butyl isothiocyanate on fragmentation because addition of the C =S bond of the isothiocyanate occurs across the less sterically hindered 0=N group of the carbodiimide. ...

A soln. of diethyl N-butylphosphoramidate in benzene added dropwise with stirring to a suspension of NaH and a little tetra-A -butylammonium bromide in the same solvent over 30 min at 50, after 2 h CS2 added in 1 portion at room temp., the mixture refluxed for 2 h, and left overnight at 20-25° butyl isothiocyanate. Y 91 % (30-50% without Bu4NBr). F.e. incl. N-aryl derivs. s. B. Oleiniczak, A. Zwierzak, Synthesis 1989, 300-1. 

Butyl isothiocyanate reacts with Bu3PbH at 0° C without precipitation of lead. After 3 hours the lead hydride is used up but not the isothiocyanate. The smell of isonitrile and the strong absorption in the N—H region at 3220 cm make it probable that reduction is the main reaction. The 1 1 adduct could not be isolated 152). 

The preparation of 5-chloro-l,2,4-thiadiazol-2-ium chlorides 95 by treatment of formimidoyl isothiocyanates 94 with a twofold excess of methanesulfenyl chloride has been reported in an unusual variation of a type C synthesis. These salts show interesting chemical behavior toward several nitrogen and carbon nucleophiles. The nature of the N-substituent determines the stability of the salt 95. When the substitutent on nitrogen is /-butyl, the salt 95 decomposes readily in solution to give the 5-chloro-l,2,4-thiadiazole 96 (Scheme 10) <2003HAC95>.

Heating of two eqnivalents of phenyl isothiocyanate with di-t-butylsulfurdiimide affords N-t-butyl-N -phenylcarbodiimide in 72% yield. ... 

The treatment of di-t-butyl diimide with r-butylketene produces the isothiazolidin-3-one and diphenyl diimide with chlorocyanoketene gives 3-cyano-2,l-benzisothiazole (Scheme 26) <83H(20)187>. The reaction of benzoyl isothiocyanate with nitroketene S,N- and JV,Af-acetals (269) (X = MeS, R NH) yields the 3-methylthio and 3-amino-3-isothiazolines (270) (X = MeS, R NH) <82S65>. 

The reaction of S-methylthiolanium fluorosulphate with thiocyanate ion gives mainly 4-(methylthio)butyl thiocyanate, result consistent with an hypothesis for the biogenesis of the latter the isothiocyanate has also been prepared (Scheme 225) N-Alkyl(aryl)-N-isothiocyanato-carboxamides were prepared by reacting the corresponding 2-chloroacetamides with potassium... 

Kim demonstrated that the substituted benzotriazoles can afford either indoles or 3-acylindoles depending on the R group (equations 2 and 3) [6]. As might be expected, phen-anthridines accompany the 3-acylindole pathway (up to 30%). This reaction is initiated by formation of an 0-stan-nyl ketyl radical and loss of N. Further cyclization and loss of either t-butyl radical or R CHO affords the indole products. Minakata, Komatsu, and coworkers generated 1,5-dipoles from either 0-staimylmethylated thioanilides or isothiocyanates that cyclize to form indoles (equations 4... 

A domino organophosphine-catalyzed nucleophilic ring opening/cydization of cyclic and acyclic aziridines with carbon disulfide and isothiocyanates providing a simple and convenient route to thiazolidinones 91 (from CS2) has been reported by Hou and coworkers [37] (Scheme 4.18). Thus, the reaction of cyclic aziridine 55 from cyclohexene (n=l) with carbon disulfide in the presence of 10mol% of BU3P in t-butyl alcohol affords trans-l,3-thiazolidine 91a in 92% yield. On the other hand, no product was obtained from aziridine derived from cyclopentene (n = 0), whereas the reaction of aziridine from cycloheptene (n=2) afforded the corresponding thiazolidine 91c in 41% yield. Similarly, the acyclic aziridines 65...
