Abstract :In this work, we consider the finite ring $\mathbb{F}_{2}+u\mathbb{F}_{2}+v\mathbb{F}_{2}$, $u^{2}=1, v^{2}=0$, $u\cdot v=v\cdot u=0$ which is not Frobenius and chain ring. We studied constacyclic and negacyclic codes in $\mathbb{F}_{2}+u\mathbb{F}_{2}+v\mathbb{F}_{2}$ with odd length. These codes are compared with codes that had priorly been obtained on the finite field $\mathbb{F}_{2}$. Moreover, we indicate that the Gray image of a constacyclic and negacyclic code over $\mathbb{F}_{2}+u\mathbb{F}_{2}+v\mathbb{F}_{2}$ with odd length $n$ is a quasicyclic code of index $4$ with length $4n$ in $\mathbb{F}_{2}$. In particular, the Gray images are applied to two different rings $S_{1}=\mathbb{F}_{2}+v\mathbb{F}_{2}$, $v^{2}=0$ and $S_{2}=\mathbb{F}_{2}+u\mathbb{F}_{2}$, $u^{2}=1$ and negacyclic and constacyclic images of these rings are also discussed.
