Support-controlled Switching of Sulphur-Nitrogen Nucleophilicity for Inorganic Solid-supported Alkaline Earth Metal Thiocyanate Reagents
A dramatic change in the sulphur-nitrogen selectivity of the SCN substitution of t-butyl bromide was observed, in addition to a dramatic increase in reaction rate, by simply supporting various alkaline earth metal thiocyanates on various inorganic solids.
Microwave-assisted synthesis of alkyl thiocyanates
Microwave irradiation accelerated the reaction of t-alkyl, allyl, and benzyl halides with Zn(SCN)2 to afford thiocyanates in excellent yields and high selectivity with the formation of isothiocyanates only in minor proportions. Because thiocyanates are stable intermediates to thiols, the method also affords facile access to corresponding thiols.

Ultrasound-assisted nucleophilic substitution reaction of t-Alkyl halides with zinc and titanium thiocyanate
Ultrasound promotes nucleophilic substitution of t-alkyl halides with ambident thiocyanate nucleophile, in the form of its zinc or titanium thiocyanate, under mild conditions to afford the corresponding thiocyanates selectively, in good to excellent yields. This improved synthetic methodology affords a facile access to tertiary thiols via the corresponding thiocyanate intermediates.
