The Bl,CI,C2 plane forms an angle of 85" with the CI,B2,C14 plane. The duryl rings are twisted by 49 and 88" with respect to the BI,Cl,C2 and C2,B2,C1 planes. The C1C2 bond of 137 pm in the three-membered ring is considerably longer than the CC double bonds in cyclopropenes (130 pm ["]) but the same
Grignard reagents such as isopropyl-and tert-butylmagnesium halide (2a: X = Cl; 2b: X = Br) react with tert-butylphosphaacetylene (1) in a regio-and stereoselective 1,2-addition process at -78 Β°C to give the 2-phospha-1-vinylmagnesium halides 3a,b in high yields. At elevated temperatures, the [ β‘] P
A novel catalytic effect of bismuth(III) salts such as BiCl 3 , Bi 2 O 3 , and Bi(NO 3 ) 3 β’5H 2 O has been disclosed in new palladium(II)-catalyzed Michael-type hydroarylation of nitroalkenes with aryltin compounds. The reaction is atom economical in the tin compounds and slightly fewer than four a
