Følgende reaktanter kombineres til dannelse af 3-chlorooctan i FATTIG YIELD.

1.Okt-2-en + hydrogenchlorid

CH3CH = CHCH2CH2CH2CH2CH3 + HC1 CH3CH2CHClCH2CH2CH2CH2CH3

(+ 2-chlorooctane)

2. okt-3-en + hydrogenchlorid

CH3CH2CH = CHCH2CH2CH2CH3 + HC1 CH3CH2CHClCH2CH2CH2CH2CH3

(+ 4-chlorooctan)

3. Octan + hydrogenchlorid + ultraviolet lys

CH3CH2CH2CH2CH2CH2CH2CH3 + HC1 CH3CH2CHClCH2CH2CH2CH2CH3

(+ 1-chlor-, 2-chlor- og 4-chlorooctan)

Og her er tre kombinationer, der giver 3-chlorooctan i Godt YIELD.

4. Octan-3-ol + hydrogenchlorid

CH3CH2CHOHCH2CH2CH2CH2CH3 + HC1 CH3CH2CHClCH2CH2CH2CH2CH3 + H20

5. Octan-3-ol + thionylchlorid + pyridin

CH3CH2CHOHCH2CH2CH2CH2CH3 + SOCl2 + C5H5N CH3CH2CHClCH2CH2CH2CH2CH3 + S02 + C5H5NHCl

6. Octan-3-ol + phosphortrichlorid + pyridin

CH3CH2CHOHCH2CH2CH2CH2CH3 + PCl3 + C5H5N CH3CH2CHClCH2CH2CH2CH2CH3 + H3PO3 + C5H5NHCl

I de sidste to tilfælde virker pyridin som en base. Det reagerer som en base for at neutralisere HCI, som det dannes.
