Bhupendranath attended the annual conference of WPP in 1927, where he met Nalini Gupta. He spread ideas of socialism and Marxism among youth, speaking about Russian revolution. Veteran Communist and TU leader Dr Ranen Sen recalled that Dr Bhupendranath used to take political classes among young revolutionaries on Marxism. Many of them later joined the CPI under his influence. Famous Communist historian Chinmohan Sehanavis recalls his indebtedness to Bhupendranath for his training in Marxism thus: "I came in contact with Shri Bhupendranath Dutta during 1933-34. When I expressed my desire to study socialism and Marxism from him", he asked whether it was for becoming a scholar or a mass worker. Sehanavis told him he wanted to work among workers and peasants.
Organizer of Students, Youth Bhupendranath was a much sought after leader. He delivered presidential address at Dacca District Youngmen's Conference in 1927. In a letter to S A Dange, on 12 November 1927, on the proposed first all India Socialist Youth Congress, Bhupendranath wrote: "This Congress is intended for those young men and women of India who hold Marxist worldview, and they only are welcome to be the delegates of the Congress." Socialist Youth Congress was held on 27 December 1927, in Calcutta. Bhupendranath as chairman of reception committee drew attention of youth to Marxism and suggested formation of study circles. Jawaharlal Nehru presided over. All Bengal Youth Association was formed at the beginning of 1928, with Bhupendranath as the president of the organization and as the main speaker at its conference. Bhupendranath also spoke at the conference of Young Comrades’ League at Rajshahi in April 1930. His speech helped many young men to give up anarchism and come over to communism. Bhupen presided over Khulna district students’ conference on 5 May 1929, Burdwan district students’ conference on 17 August 1929, Faridpur students’ conference in June 1931, and others.

He along with
Hiren Mukherjee and Humayun Kabir attended BPSF conference on 12 October 1936.
