资源简介:
Simple two-coordinate acyclic silylenes, SiR2, have
hitherto been identified only as transient intermediates or thermally
labile species. By making use of the strong σ-donor properties
and high steric loading of the B(NDippCH)2 substituent
(Dipp = 2,6-iPr2C6H3), an isolable monomeric species, Si{B(NDippCH)2}{N(SiMe3)Dipp}, can be synthesized which is stable
in the solid state up to 130 °C. This silylene species undergoes
facile oxidative addition reactions with dihydrogen (at sub-ambient
temperatures) and with alkyl C–H bonds, consistent with a low
singlet–triplet gap (103.9 kJ mol–1), thus
demonstrating fundamental modes of reactivity more characteristic
of transition metal systems.
