Therefore with the acetylide as the nucleopile: 个 HO* R'一C=C+ R'-C=C-C-0 R'一C=C-C一OH R acetylide aldehyde an acetylenic alcohol or ketone E.g. C=C-H 1)NaNH2 C=C-CH2-OH 2)H2C=O 3)H20 Ch09 Alkynes (landscape) Page 7Ch09 Alkynes (landscape) Page 7 Therefore with the acetylide as the nucleopile: E.g. C C H 1) NaNH2 2) H2C=O 3) H2O C C CH2 -OH
