For the first time, a general method for catalyst-free and solvent-free hydroboration of various aldehydes has been developed.
Abstract Vinylsilanes are highly appealing and convenient chemical derivatives, as evidenced by the increasing number of synthetic transformations utilizing this class compounds. Herein, a new comprehensive cobalt‐catalyzed procedure has been developed enabling selective hydrosilylation internal aryl‐, alkyl‐, silylalkynes. Cobalt complexes bearing triazine‐based PNP pincer‐type ligands provide exclusive syn ‐addition primary well secondary silanes to C≡C bonds. As result, ( E )‐silylalkenes...
Owing to their versatile application possibilities, silsesquioxanes (SQs) are of considerable interest for creating hybrid inorganic-organic materials. In this report, two novel and independent strategies the direct attachment boron functionalities presented. Encouraged by our previous work concerning synthesis borasiloxanes through catalyst-free dehydrogenative coupling silanols boranes, we decided apply method a various boron-functionalized silsesquioxanes. During tests, also investigated...
Herein, we report that a cobalt catalyst permits the general synthesis of substituted alkynylsilanes through dehydrogenative coupling and hydrosilanes. Several silylated alkynes, including di- trisubstituted ones, were prepared in one-step procedure. Thirty-seven compounds synthesized for first time by applying our system. The bearing hydrosilyl moieties provide an opportunity further functionalization (e. g., hydrosilylation). use primary silanes as substrates precatalyst activators...
The reactions between silanols or terminal acetylenes with alkynylgermanes have been accomplished using potassium bis(trimethylsilyl)amide as the catalyst. This strategy has provided an entry point into various organogermanes including germasiloxanes and alkynylgermanes. Remarkably, not only KHMDS but also simple bases such KOH can serve efficient catalysts in this process.
Apart from some specific synthetic solutions, a dehydrogenative coupling of silanols with hydrosilanes seems to be the most atom-economical and practical method for formation unsymmetrical siloxanes.
Abstract A cobalt‐catalyzed addition of hydrosilanes to unsaturated carbon‐oxygen bonds has been developed, relying on complexes featuring easily accessible and inexpensive PNP‐type pincer ligands. wide range heterocyclic, aliphatic, aromatic ketones, including those containing both electron‐donating electron‐withdrawing substituents, were transformed into silyl ethers or secondary alcohols with high yields. An important feature this protocol is that silanes can act as the substrates...
The formation of several silyl ethers (alkoxysilanes, R 3 Si‐OR') and unsymmetrical siloxanes (R Si‐O‐SiR' ) can be catalyzed by the commercially available potassium bis(trimethylsilyl)amide (KHMDS). reaction proceeds via direct dealkynative coupling between various alcohols or silanols alkynylsilanes, with a simultaneous gaseous acetylene as sole by‐product. dehydrogenative dealkenative are well‐investigated, whilst utilization alkynylsilanes silylating agents has never been comprehensively...
Herein we report a strategy for the synthesis of organosilicons, including siloxanes, silyl ethers, and aminosilanes,
