摘要:... Also, hydrostannation reaction of the diyne proceeded well in a trans -addition manner to give the corresponding vinylstannane in high yield. The vinylstannane was also found to be effectively convertible to CF 3 -substituted cis -enediynes in high yields.

摘要:Abstract(#br)Hydrostannation reactions were performed cleanly using ionic liquid supported organotin reagents. These green reducing agents were used both under free radical and palladium-catalyzed conditions. One of the new ionic liquid supported organotin reagents so obtained wa...

摘要:Abstract(#br)Hydrostannation of mono- and disubstituted alkynes with trineophyltin hydride ( 1 ) leads to vinylstannanes in good to excellent yields, the configuration of the products depending on the reaction conditions. Thus, whereas hydrostannation under radical conditions...

摘要:Abstract(#br)The palladium catalyzed hydrostannation of 1-alkenylphosphonates gives the ( E )-α-stannyl 1-alkenylphosphonates 2(#br) stereospecifically. 2(#br) can be transferred to α,β-disubstituted vinylphosphonates with the retention of the configuration.

摘要:Abstract(#br)The hydrostannation of activated alkynes proceed in good yields and high regioselectivities catalyzed by CuCl, in the presence of potassium tert -butoxide, triphenylphosphine, and tributylstannane, by generating copper hydride in situ.

摘要:Abstract(#br)This paper reports results obtained in a study on the palladium-catalyzed hydrostannation of substituted propargyl alcohols with the bulky trineophyltin hydride ( 1 ). The reaction of 1 with 10 propargyl alcohols containing one up to three substituents, was carrie...

摘要:Abstract(#br)A one-pot hydrostannation/Stille coupling sequence amenable to the employment of acid chloride electrophiles has been developed. In this protocol, palladium mediated alkyne hydrostannations using Me 3 SnF/PMHS as an in situ trimethyltin hydride source are followed ...

摘要:... The study of the free radical hydrostannation of mono- and disubstituted acetylenes with hydride 3 shows that they are stereoselective and that the stereoisomers obtained in higher proportion are stable and easily separated by column chromatography. Some preliminary studies ...

摘要:Abstract(#br)Photochemically activated [Mo(CO) 6 ] and [Mo(CO) 4 (η 4 -nbd)] are demonstrated to be good catalysts for the hydrostannation of norbornadiene (nbd) by stannyl hydrides ( n Bu 3 SnH and Ph 3 SnH) to give stannylnorbornene in ca . 100% yield. The reaction was carrie...
