Beyond Dehydrocoupling: Group 2 Mediated Boron-Nitrogen Desilacoupling.
The alkaline-earth element bis(trimethylsilyl)amides, [Ae{N(SiMe3 )2 }2 (thf)2 ] [Ae=Mg, Ca, Sr], are effective precatalysts for boron-nitrogen bond formation through the desilacoupling of amines, RR'NH (R=alkyl, aryl; R'=H, alkyl, aryl), and pinBSiMe2 Ph. This reactivity also yields a stoichiometric quantity of Me2 PhSiH and provides the first example of a catalytic main-group element-element ...
متن کاملAlkali metal-mediated dehydrocoupling of Me2NH·BH3.
Bis(trimethylsilyl)amide derivatives of the group 1 elements (Li, Na, K) are competent pre-catalysts for the dehydrocoupling of Me2NH·BH3 via the formation of intermediates containing [H3BNMe2BH2Me2N](-) anions.
متن کاملStoichiometric and catalytic Sn-mediated dehydrocoupling of primary phosphines.
The room-temperature reactions of stannocene, Cp*(2)Sn, with a range of primary phosphines, RPH(2), result in diphosphanes [RP(H)P(H)R]. The reactions involving Cp*(2)SnCl(2), however, result in catalytic dehydrocoupling; the first example of main group metal catalysed dehydrocoupling to be identified.
متن کاملBoron-oxygen luminescence centres in boron-nitrogen systems.
Closed-shell BO(2)(-) and BO(-) anions are proposed as high-efficiency luminescence centres in boron-nitrogen systems, which makes the anions localized and leads to a radiation transition.
متن کاملMicrofinance Beyond Group Lending 2.PDF
Microlending is growing in Eastern Europe, Russia and China as a flexible means to widen access to financial services, both to help alleviate poverty and to encourage private-sector activity. We describe mechanisms that allow these programs to successfully penetrate new segments of credit markets. These features include direct monitoring, regular repayment schedules, and the use of non-refinanc...
