Rh(SbPh3)3(CO)X (X=Cl (1), Br (2)) react with HCCCH2Y (Y=Cl, Br, OTs, OBs) in CH2Cl2 at ambient temperature to afford the η1-allenyl Rh(SbPh3)2(CO)X(Y)(η1-CHCCH2) (X=Cl, Y=OTs (3a), OBs (3b); X=Y=Br (3c)) and the rhodiacyclopent-3-ene-2-one Rh(SbPh3)3Cl(η2-C(O)CHC(Cl)CH2) (5a) and Rh(SbPh3)3Br(η2-C(O)CHC(X or Y)CH2) (X or Y=Cl (5b), Br (5c)) products. The corresponding reactions of Rh(SbPh3)3(CO)X with
五坐标铑(I)配合物锑化氢的Rh(灰飞虱3)3(CO)X(X =氯(1),溴(2)),与HCCCH反应2 Y(Y =氯,溴,在职培训计划,OB的)在CH 2氯2在环境温度下,得到η 1 -allenyl的Rh(灰飞虱3)2(CO)X(Y)(η 1 -CHCCH 2)(X =氯,Y =在职培训计划(3a中),OB中(图3b); X = Y = Br的(图3c))和rhodiacyclopent -3-烯-2-酮的Rh(灰飞虱3)3 Cl(上η 2 -C(O)CHC(Cl)的CH 2)(5a)和Rh(灰飞虱3)3 Br(上η 2 -C(O)CHC(X或Y)CH 2)(X或Y =氯(5B),溴(5C))的产品。的Rh(灰飞虱的相应的反应3)3(CO)与MeCCCHX 2 ý得到η 1 -propargyl的Rh(灰飞虱3)2(CO)氯硅烷(OTS)(η 1 -CH 2 CCMe)(
