摘要

Abstract A number of allenes RR 1 C [DOUBLE BOND] C [DOUBLE BOND] CHR 2 2 have been prepared by interaction between acetylenic tosylates R 1 C≡ CCHR 2 OTs, 1 (R 1= H, alkyl, aryl, H 2 C [DOUBLE BOND] C (CH 3) or CH 3 C≡ C; R 2= H or tC 4 H 9) and organocopper (I) compounds “RCu”(formed from Grignard compounds RMgCl or RMgBr with R= alkyl, aryl or 2-thienyl and copper (I) bromide in tetrahydrofuran). If R= tC 4 H 9 the ...
